A note on Collarspace's 'WYSIWYG' (what-you-see-is-what-you-garbled) editor for messages and profiles:

This editor should be called 'delete-it-or'. My (still growing) list of deletions of character strings goes as follows:

a) 'a-s-p-' is deleted from words like 'gr-a-s-p-' (becomes 'gr...' [indeed ...]), 'a-s-p-irin' becomes 'irin' etc.;

b) 'f-o-r-m': "in-f-o-r-m-ation' is reduced to '...ation', de-f-o-r-m-ity is de-f-o-r-m-ed to read 'deity' (quite subtle, ain't it? - Don't know if atheists like that); and 'platf-o-r-m' then reads 'plat' or uni-f-o-r-m reads 'uni';

c) 's-p-a-n' is deleted too, so 's-p-a-n-king' will render as '...king' (for those who are into queening?) and 'attention s-p-a-n' will leave no trace but 'attention' (yes ... you were saying?) ... and those Hi-s-p-a-n-ics from S-p-a-n-ish speaking countries are speaking -ish from the -ish lands where Hi-ics tend to dwell - Tolkien would be impressed, after all, it cost him far more effort to design new languages;

d) 'f-i-n-i-t' as in 'de-f-i-n-i-t-ion' will then read 'de-ion' (and I thought I had missed a Greek loan-word the first time I encountered that one) ... (However, if you write de-ion without that hyphen in the first place, it will be 'corrected' to read: de-scrip-tion. Oh my.)

I'm sure the list goes on ... until all correspondence, even that of the most erudite, will be reduced to Twitter f-o-r-m-at (phew, I caught that just before saving).

But no, no, it does not stop there - sometimes Collarspace recycles some of these character strings to perfect the charade:

's-u-b-j-e-c-t' becomes 'sub-j-a-s-p-ect', 'p.r.o.j.e.c.t' becomes 'pro-j-a-s-p-ect' and should you have 'ex-p-e-c-t-a-tions' then consider to live with 'ex-a-s-p-e-c-tations' ... and so on. Ex-a-s-p-erating, sorry, exerating in CS style resp. diction.

Now I sit back and wait till the World Scrabble Federation accepts these neoplasms, maybe then we can all have a BDSM scrabble tournament called 'the 50 nightshades of babble'. No, no, I am not a particularly funny character, what makes you think that? Reality is far funnier than any stuff I could make up.

And be advised: all software in your Smartphones and self-driving cars is of course bug-free - it's never a bug, it's a feature.

So, if I should have inadvertently used such a character combination in my current communication with you (or anywhere in my profile) and it is missing when you (try to) decipher my well-intentioned orthographic efforts, then the above is the reason, not excluding my own occasional glitch as an extra excuse.

Whom does this profile address? (Who is it for? Is this you?)

First and foremost I would say, I am looking for slaves, but would consider all submissives too who feel they might have strong slave tendencies. 

To begin with and to set at rest some reservations you might have: both my pictures as well as my age are real. I won't post face pics for the simple reason that in some niche circles I am a kind of celebrity and might easily be recognised with many unintended consequences. I even need to be careful with my biographical excerpt (which you find below) lest someone who knows me better might count two and two together and decode it.
I know it sounds boisterous, but I do not look my age, to many I look like 40 at most. My face and body have no wrinkles to speak of (and I did not opt for elective surgery like Berlusconi nor would I condone Botox either). This is just an abstract, more about me further down below.

Back to more about you:

You should be in this for the long haul. This is the reason why I have tentatively set the age preferences as between 18 and 40 for subs or slaves.

The reason is this: if from here on out we would envisage a long-term relationship, and under an LTR I would understand something to last for decades, i.e. maybe thirty years or 'till death does us part', then most people would have a hard time to keep in synch with my slowed to almost reversed ageing process (which so far has almost come to a standstill - more on that later). So of necessity I need to choose from an age bracket who would in such a time frame not likely 'overtake' me with regard to their physiological age as compared to mine. Neither would I want to run a nursing home nor would I want to lose you due to developing health-related incompatibilities with the BDSM life-style.
When I look at the age bracket of 18-40 and consider the average profiles at the lower and high ends, on the other hand, I feel I value maturity to a certain extent and this means I might predominantly search from 25 year-old upwards and for many candidates 35 years might be the threshold to keep up with my physical condition.
However, let not this deter you to contact me, should you consider yourself either mature at an early age (I've met a few, very few though, 16-year-old women who were more mature than many men in their fifties; and I know of a German gymnast, who still competes regularly, and she is beyond ninety, while I know, most men in their twenties couldn't work the parallel bars, let alone compete).
In the last analysis I, or we, will decide once we discuss per mail, chat or meet face-to-face, long before either commits to anything. Which brings me to the concept of a probation period:
Whoever you are, however beautiful you may be, I will give us both always a probation period of 100 days. I won't fall for appearances only (although these can help …), as they may change over a period of thirty or more years, but to make such (a) relationship(s) work in an enduring fashion requires more than just an initial excitement and sheer physical attraction.
And to find out where we both stand, I believe 100 days of 'courtship' should be sufficient, because, on the other hand, a never-ending probation is incompatible with lasting trust as well. Somewhere down the line you 'have to tie the knot', so to speak, or else let go.
Now, I am well aware, that there is no binding irrevocable contract in BDSM slavery (not in the sense that it could be upheld in a court of law). You could pack your bags and be out the door at any minute, even on day 101. For me though, the difference is that after 100 days I am willing to commit to see this as a true long-term commitment from my side which e.g. would entail not letting some transient conflict call into question the whole relationship. Rather, such an event would call for a thorough one-on-one talk and 'couple therapy'. In my book, there is a marked difference here and hopefully during these first one hundred days I get to know you so well that I can expect the same mechanism of wanting to see things through in good times and bad will have come into force on your part as well.
As for daily routines, household rules and regulations and by-laws, and how I would expect you to allow yourself then to be groomed and developed, also on the mental, spiritual and intellectual planes, see below in the respective chapter.
Now, as regards compatibility: I would suggest you look at my interests in the respective section and review them to see whether they resonate with you and to what extent. If there is a gross mismatch and you still wanted to apply I would suggest you either haven't carefully selected and stated your interests in your profile or you consider yourself so malleable in light of what you expect to gain from my personality in other areas that you either did away with some of your incompatible cravings (postponing is no option, it will probably never come to pass or 'get better' - during that time of 'seeing it through' by putting yourself last you might well have found a choice of partners more ideally suited to you) or you actually now perceive them as less strong and are ready to change course to some extent. Your decision - however, a decision you will have to live with, so choose carefully.
Likewise, if you read the whole profile and don't at least tentatively 'get wet', get horny or it doesn't resonate on a deeper primal level with you, then we may not be a good match either. Again, don't waste your time (or mine) if this might lead to heartbreak and hardship instead of affection, love, arousal and bliss for you. Many profiles here bear witness to D/s relationships gone sour, then bad and worse from there. This includes slaves who faithfully served a 'master' for years only to be kicked out at short notice and then finding themselves in a homeless shelter. I doubt if it is a good idea to, from that precarious position, solicit a new 'master' (immediately) to take one in, from the fry-pan into the fire. 'Woman forges her own destiny', the saying goes. Yes, yours, but don't make that ours.

A bit about me (biographical abstract)

When I grew up, the world was neatly divided between East and West, communism and capitalism, the Korean war had just ended when I was born, and every so often we'd have drills to exercise for a nuclear contingency. Not all people in my home country were well-fed yet, while by now not many are not obese.
From an early age, when my schoolmates would read novels, I would prefer science books (although I did read adventure stories from time to time too). I began to 'study' chemistry before I could even read or write. Which meant that by the time I got to university I was bored to death, but they wouldn't let you in above undergraduate level no matter what. You had to 'get the credits'.
Well, this led to me taking on other subjects and from then on I was 'hooked'. I never stayed in one profession for longer than five to ten years, meaning that when I became proficient and even most time 'best in class' at something, I would then switch to a totally unrelated area of expertise, which led me through brushes with the legal profession, insurance consultant, I owned a building firm, even today there are a few people who still want to consult my expertise on concrete chemistry, be it for leaking garage roofs or public motorway bridges and hydro-electric dams suspected to collapse. The latest incarnation which I am about to say goodbye to was ERP consulting (if you don't know that term, either look it up or don't bother - and I deliberately have not posted explanatory links in this profile lest it might not get approved due to a suspicion of linkbaiting). I did warn some friends who would listen of the Dotcom bubble back in 1999/2000 and of the 2007 real estate/mortgage bubble, both of which I called in good time, though few would heed the advice (and we're right in the next bubble now as of this writing).
I have six full professional qualifications 'under my belt', even for professions I never had time or an appetite to work in and I would have another dozen more if the dates of the exams were not only once per year and always when I would be unavailable due to the obligations of my Europe-wide travels on some consulting business or other.
While I did have several relationships that could qualify as BDSM activities proper, I could never arrange any kind of long-term live-in course of action because when you work in one city this week, in another city next week and live from a suitcase, and you work long hours, at times not leaving the office because by the time you finished your day's work, you look at the clock and a new day has broken and you can just grab another coffee and stay where you are, then you cannot be a Master or Dom to a slave, let alone slaves in the plural.
This isn't to say I didn't have long-term relationships too, but they were all of the vanilla type and the kids from these relationships are all grown. Only now am I truly free not only of outlasting commitments and the moral obligations that go with those, but also will scale down my work commitments soon (ah … hopefully), and settle down. I haven't finally decided where that will be, but Switzerland is a strong option and having worked there for quite a while I am entitled to stay there should I so choose. But not all bets are off yet, although it definitely won't be overseas (from a European perspective) but it will be in Western Europe including the UK or Ireland, I should think.
"Why has he prepared this profile now if he hasn't even decided where to live?" you might wonder. Well, precisely and mainly for two reasons:
Because as long as the silt is still in flux, it can yet decide where to settle and that could likewise be (a) (first) slave(s) country (or a Domme's according to the specifications herein), who already are settled down and who are wont to leave but might consider taking in their Dom/Master and/or partner. This is by far not the main thrust of the profile but for completeness' sake it is another option. And looking at it from the other side of the same coin, all those, who have been on Collarspace a little longer or had tried to find a suitable (let alone 'ideal') BDSM partner through other means, will agree, that this can be an excruciating process that takes months in most cases and sometimes years, if you make the wrong choices, get bruised and then have to recollect yourself and start all over again not having got any younger (but hopefully wiser). If I had bought an estate or whatever before deciding on at least a first partner in life who met the stipulations laid out in this profile, but she would live in another country (or in the same country, but further away) and for some personal reasons could not readily relocate, what stupid investment would that homestead then have been. And if you are even only superficially familiar with real estate markets, you know full well that selling a house after just having got the deeds in your name puts you back a least ten percent of the purchasing price (plus cost) just spent, even if you could sell it for the exact same price and find a buyer immediately. So, God forgive, it's the consultant in me that makes me think things through in all directions, and the higher the stakes, the more diligently.
This maybe an unusual approach, you might say, however, as a consultant who earned his daily bread by helping boardrooms to find options they would not have otherwise considered, I believe this is a more than legitimate approach. Some of you might even have a business (or be heir to a business) that you could imagine might thrive even better with a seasoned consultant as a sidekick (or be revived if currently in trouble). Mind you: this doesn't take away one jot from the compatibility requirements alluded to earlier - we should be a good, even close to ideal, match to begin with, and not let ulterior economic calculus influence our affairs of the heart.
To all of you for whom 'size matters': I won't discuss the other thing in public, except, let it be said, that if my pictures are not discernible as me being of the more virile type, then I put this down to lack of experience of the beholder. But as for my height, it's been truthfully stated in the profile. If you prefer the taller type, then well and good and good luck with your search. I'm not the 'long and lanky and bony' type and I never really felt it to be a problem. On the contrary, I was always happy to walk through doors and get into cars without hitting my head. And those schoolmates and later the fellow students who had to duck their heads while walking through normal-height doors, now, without exception, complain about back problems. Looking back over the years, all my female partners were either slightly taller or, with just one exception, at least taller than me when wearing high heels. Still, we both always had a good time while it lasted.

Who and what you should not be (activities not supported, fetishes not condoned) (start)

Without taking away anything from any statement made heretofore and hereinafter, these are things you might want to consider and advice you might want to heed before you apply, or contact me:
I probably won't do anal. The reason is that practically all the nerves hard-wired in our brains for sexual pleasure are in the clitoris and the vagina if you're female and in the glans and shaft of the penis for males.
Oral is different in that there are moving parts (tongue, lips, gums, palate, cheeks) that can be skilfully applied in furthering arousal and the inside of our mouths as well as our lips again are among the most innervated parts of the body and made for sensual experiences (hence kissing became popular).
In my book, these are multitudinous options and variations that we will never finish exploring. Since anal brings with it a considerable risk of infection through intestinal bacteria and fungi (q.v. vaginal mycosis and sometimes worse) I consider the risk of anal greater than the reward. I know, many, maybe even the majority of CS members may think otherwise, but, being in the majority, they should not have problems finding other adequate partners. Please consider this before applying.
If something that I don't do or don't allow is high on your list, then better abstain than later be sorry. An unfulfilled craving can be outshone by overwhelming first excitement, but in the long run there is always an unfulfilled longing that finally gets the better of the 'craver'. Behind each and every extra-marital affair or adulterous behaviour there is a craving that has not been adequately addressed by their incumbent partner. This is the opposite of a mutually fulfilling LTR, don't you think?
And may I warn you: tickling is, I believe, much underrated in the life-style. In my experience, in light of research of the subject of D/s and SM, and in my personal opinion, tickling is the only arduous BDSM activity that can be scaled infinitely, from the slightest tease, a barely noticeable breeze, through endorphin-releasing convulsive laughter, to true torture at the other extreme. So if you are not OK with that, again I suggest you would do yourself a favour if you moved on.
Having cleared that out of the way, all other activities that you would be forced to submit yourself to, would probably be more 'mainstream' except for illegal activities like involving children or animals, toilet stuff, body mutilation like permanent marks, extreme dilation, etc.

Physique, fitness, body modifications etc.

If you are moderately overweight, this can be rectified and then stabilised successfully under my guidance. I will not hold that against you if you qualify in other areas.

Who and what you should not be (activities not supported, fetishes not condoned) (continued)

You should not have implants, as they are, for the time line envisaged here, a considerable risk and anyhow, whatever the size of your breasts (this is a factor that can not be judged on its sole merits alone), the important point is that they are natural and did not undergo elective surgery. The same goes for your lips, no 'puffing up' with silicone. Apart from the fact that you can't see each other's lips while kissing anyhow, and that such artificial enhancements actually do not add to the sensuous experience, they, if anything, can have a numbing effect.
Same applies to Botox: this is a paralysing poison and I see no value in applying an anaesthetic to people who want to indulge in practices that are invigorating above and beyond what vanilla life holds in store. Plus, if you didn't know: Botox has an effect on your mood: as much as you get a wrinkled face when you laugh or smile, you can also enhance your mood if you fake a smile. But this can only work if your 'wrinkling apparatus' is still intact.
Also, I wish you had no piercings, though I make an exception for pierced earlobes for earrings which some girls get done even at kindergarten age. But no pierced lips, noses, tongues or clits please! As for pierced nipples: this I'll decide on a case-by-case basis, but, if you are considering getting them done while also considering applying, please postpone the former until you know the result of the latter.
Likewise, I consider tattoos potentially harmful, apart from the fact that I find smooth unadulterated skin much more titillating than looking some computer game dragon in the maw while licking your pussy or being invited to spell the nicknames of bygone love affairs …
Like with implants, I would also not advocate body modifications (other than those achievable by training, stretching and the like, see below), so if you are into that, look elsewhere. Breath play/choking is a thing that needs to be well understood, so this will be a rare event. Somewhere on the net a paramedic who is into BDSM wrote a piece titled "Submissive women kvetch" - maybe you care to read his remarks on the risks that come with oxygen starvation.
Having children: I have had my children, who are all grown and have jobs by now and hence I got a vasectomy over ten years ago. Should you wish to have children with your dominant partner at some stage, then the position offered here definitely is not for you, even if everything else would seem like hand in glove. Believe me, you should not forego your desire to have children for any other pastime, be it a career or an otherwise coherent partnership.
Equally, if you already have under-age children, again, this would not be a good match. While I have raised more step children than I had my own (two-digit altogether) and I know the stepfather business inside-out, for that very same reason I know this is a new life and I can't take on this responsibility nor would I want to neglect it at a 'single' parent's suggestion.
Pets are a similar issue. I've (or my children) had pets, like rats, rabbits, dogs, cats, guinea pigs and I know enough to know how this would be a distraction or else we wouldn't meet their animal needs, which would be a shame as well.
You should not be smoker, even a 'casual' one, nor should you do drugs or be on life-long medication, nor should you have been a heavy smoker in the past, even if you believe you've shed that craving for good - there is damage to your body on the cellular level that likely will persist. While I've consumed alcohol on social occasions and have some idea of how to choose wines, writing this, I just noticed I haven't had a drop of alcohol in the last three years (there just was no adequate social occasion and drinking alone is often a sign of budding addiction). So don't expect alcoholic beverages to figure high on our shopping list.
Last, but not least: if you have baggage like going through a divorce, well, first see it through. If you are from a culture where you honour family above all and look after each other and expect to make remittances to them in their home country to help them cope (like many Asian family members are expected to do), well again, that would be beyond our means and scope. Of course some of you will have some family but neither can we support them all nor can everyone visit, like: parents, aunts, uncles, grandparents, children, ex-spouses (?) at Easter, Christmas and each other's birthdays. It's already difficult to keep our daily routines down pat and … it's difficult enough to find appropriate accommodation as it is …
As for some of your other personal preferences: you should not be a "little" as I am not a "daddy", even if your parents, even if your grandparents are my age or younger. Equally, you should not be a gerontophile, as I can not even act the part; 'bodily speaking' I am more agile and stronger than most 25-year-olds, i.e. except maybe the ones in the top one or two percentiles. See also my explanations on the science of longevity below. Consider me rather a coeval partner in most areas, except maybe when it comes to experience and intellect.
And if you are into Dolcett: this is an interesting form of edge play, but only if it is play. Anything truly endangering your life and health and welfare in real life is not what I am going to abet.
Likewise, I won't share any of my precious possessions with others, but keep all our little 'secrets' closely guarded; so, if you are into that, or munches, gang-bangs, being whored out and other explicit interactions with strangers, seek elsewhere. 'Not for the life of me'.

What you may gain in the bargain apart from being constantly aroused

As I intimated before, a certain time of your stay will be dedicated to serious studies, the subject yet to be determined depending on individual abilities, faculties, to a certain degree, preferences (remember: I am your master then, so I decide), and previous experience. The reason is, that no one knows how long things last and I want you to have some job perspective should you decide you wanted to leave, should we both come to the conclusion that we had reached the end of the rainbow, or maybe you all of a sudden detected your vanilla side and wanted to have a normal family life with someone else. No one knows for sure and I suspect that such relationships as ours are more likely to endure if each partner was at rest with regard to his or her outside perspectives (and, in comparing them, all the more decides to stay …).
"What do I need that for?" you might say, "I am a lawyer, I have a degree from Harvard!". Well and good, but in all honesty: after a ten-year hiatus, what chance would anyone have, women especially, to find a professional position even remotely adequate to the one she left ten years before? And even if my name carried weight in the consulting world then still, you could hardly name me as a reference in this case, could you? "I spent weeks on the wooden horse, a year and three months in a cage, have experienced the cane and the crop and was held in chains and now I consider myself qualified as a human rights lawyer …". Quite.
Also, sometime after the position has become 'permanent' in the sense afore-defined after probation, I would eventually set up a fund for each slave endowed in such a way that the principal and interest or dividends accrued should make up in a way for the time spent off the workforce, again should you need to or want to dissociate yourself from the project or if it came to an end for whatever reason.
On top of the material facets which should not sway you one way or the other, though, this whole project is about self-actualisation (cf. Maslow) and self-fulfilment by doing your Master's bidding, knowing full well that he eventually gets to know you better than you yourself.

Hypnosis, Relyfe, (auto) Suggestions

The interest in sexual/erotic hypnosis and things like relyfe reprogramming seems to be on the rise. Before I was grown, I had already bought and read my first book on hypnosis. This was shortly before or around the time Dave Elman's posthumous book on hypnotherapy made rapid inductions widely known and eventually accepted (though that book I read would have none of it, the author hadn't heard of the latest developments yet).
Later, in the mid eighties, I was training in NLP under one of the first master practitioners that Richard Bandler and John Grinder had licensed in my country. And yes, I have read the latest book on relyfe programming/pillow talk too. All these are options. However, this is potent stuff and can alter your personality (after all, that is what you'd want, if you were so inclined). And seeing what hypnosis etc. is and does, I would rule out using anything like that on you during the probation period (see above), no matter what you'd ask me to do. While consent is a prerequisite for successful hypnotic interventions, I am quite reticent to use these terrific and potentially disruptive tools on anyone whom I might not be able to monitor for at least, say, a year after implanting the suggestions. So, yes, it's an option, but not for the total novice.

Things considered an asset in your application

The following doesn't mean I won't consider English or German speakers. Quite contrarily, the majority of all 'letters of interest' will likely from these two language groups; I just wanted to make sure not to discourage all the others, but call everyone to the fore.
Both of my parents were interpreters and out of that family tradition I became a linguist too, though this is one of the fields, as alluded to above, that I do not work in, despite my professional credentials. However, there are still several languages on my list that I want to either improve upon (Dutch and French) or even master, although I do not yet have but a basic understanding of some of them. The foremost of the latter is Portuguese, which I consider the most melodious language in the world, and that I fell in love with when I first heard it spoken and when I heard recitals of Pessoa or some fado performances. So if your native language is Portuguese, either from Portugal or Brazil, or maybe the former colonies too (if it had been your native tongue there), that would be a plus. Same goes for Dutch, so if you are from the Netherlands or the Flemish part of Belgium (I doubt you still find native speakers in the Congo though) that would be an asset; in lieu of that I might also consider Afrikaans, although that will spoil my pure-bred Dutch faculties forever.
Other options are a Slavic language (Russian, Polish, Czech etc.), a Scandinavian language (Norsk, Sverige, Dansk) or Finnish, Lithuanian (for its relation to extinct Sanskrit) or Estonian, Latvian, then Chinese or some of the languages of the Indian subcontinent like Hindi (foremost) or maybe Telugu, Urdu, Bangla. Thai is another option, and then of course Spanish, Romanian, Rheto-Roman as runners-up together with French. I'd even consider Gaelic, Icelandic and other languages with lesser numbers of speakers. But please be aware: I require perfect first-language (native, 'mother-tongue') skills. Just as many West Indians speak a broken sort of English, other nations have similar issues, like not all Franco-Canadians are good, let alone native, English speakers. And real bilingualism requires parents who each had a different native language and who both spoke to their child in their own respective language continuously. If this was done intermittently only, then the second language competence is usually flawed.
Also, if you have certain academic (or similar) credentials, this might push you to the front of the queue. While I am fairly well versed in chemistry, law and business administration (to name a few) I e.g. never got down to get my head around mathematics at the level that so-called pure mathematicians are trained to do. They play in a league of their own and even most physicists, let alone engineers, are just copycats who learned their formulas by rote but never got to a deeper understanding. Of course, philosophy or any other 'wisdom' that will enable you to hold an in-depth conversation will be appreciated too. If you think gender studies are part of the science family, you should think again, though.
What if you flunked high-school though?
Well, in one of my incarnations in business I was the (pro bono) founder and principal of a K12 school (it went by another name in another country but since most CS members are from the United States, this is the best equivalent - and UK members etc. can look it up) and I know a lot about, and even advanced, the techniques of suggestopedy, speed learning and reading, and mnemonics. So that can be handled, however, only if you are willing to learn and maybe then catch up on your high school diploma, 'matric' or equivalent in due course. If you want to spend the time you're not 'used' in a hammock, you're barking up the wrong tree.
There are other vital facets to this too, which I will deal in extenso under the longevity heading, but one deserves emphasis at this point too: mental as well as muscular activities build brain cells and their connections (synapses and so on) - it is either 'use it or lose it' and with each year of mental and muscular underload, your brain will actually shrink!
If nothing else, my tutelage will also inoculate you against Alzheimer's disease and the like (seriously - and notwithstanding other inoculations).

Project Longevity (start)

As I have mentioned several times in passing above, I consider myself a rare specimen when it comes to ageing. There is an expectation in the population at large, including among all medical doctors, that with age cometh frailty, porous bones (osteoporosis), hunchbacks, disc prolapses, wrinkles, reduced libido and eventually impotence, certainly after death, although necrophiles … (just joking). And we're told, there are certain 'age-related' diseases.
Now, while this is observably and statistically true, it is not an inevitable occurrence. If people knew better, they'd also be healthier. Consider this: the average maximum age of any population has not increased for thousands of years, it may actually have decreased since the stone age. You can easily verify this on: -ourworldindata.org/life-expectancy-.

Before humans settled down and became farmers, average height of men often reached 1,80 m (about 5 ft. 9), which can be ascertained by bone finds from that period. After that, farmers and members of their households often measured only 1,50 m (just under 5 foot) to 1,60 m (under 5 ft. 3) - just consider the suits of armour of knights in the middle ages.

Only in the 20th century has this trend been markedly reversed, due to better food and better hygiene and prenatal care and paediatric medicine etc.

What leads to these processes commonly called 'ageing' is a repetitive shortening of so-called telomeres on the human genome/chromosomes and the incremental methylation of human DNA, so that each new cell generation, most cancers excepted, becomes a little less vital than the one before. This begins at the early age of 25 (if no counteracting measures are taken) and leads to the usual septuagenarian beginning to rely on walking aids, hearing aids, getting brittle bones, a reduced immune system and being prone to falls from which he or she recovers more and more slowly as times goes on; hip fractures seem to be popular these days.

Due to our innate genetic clock, our bodies also set in motion a process called 'sarcopenia' which is Greek and means 'reduced flesh' or in other words, atrophy of the muscles. This is, by the way, the sibling of osteoporosis even if most doctors don't know it (see below).
From the time you turn 40, you, as a rule, lose roundabout 1% of your muscle mass per year, which then accelerates by the age of 50 and from then on even makes you 3% weaker each following year (whether you're a man or a woman). Of course, you don't end up with no muscle at age 80 (10% till 40, then 90% in the following 30 years), these 3% are chipped off of the remainder of what the ravaging preceding years have chipped away at, but by the time you're 80 you will, on average, have only about one third of the muscles mass left that you commanded over when you were 40. And since each muscle fibre is controlled by a motor neuron in your brain, you will also have shed similar amounts of brain mass (since the other half of the brain is busy providing your intellectual faculties, you are not reduced to one third of a brain but only to a fraction relative to the part that's coordinating your muscles; if you still lead an active intellectual life, like some retired professors would, that part of your brain would keep healthy and constant. In fact, it might even still grow -or become denser, to be precise, as your hardened skull prevents it from bulging- since learning new or additional things at any age increases brain capacity. Now, Stephen Hawking may be the prime example of this who might have a reduced amount of motor neurons but far more 'intellectual' brain connections than maybe even Einstein.
Since bones are the foundation of what allows muscles to act upon them and thus keep your skeleton up straight and allow it to move, lift weights, sit down, get up etc., your bones will dwindle in lock step with your reduced muscle mass and strength, because your body will only 'pay' for the upkeep of structures that it actually needs. This is well-known in astronauts who spend weeks in space at zero gravity and lose both muscle and bone mass to such an extent that those serving the longest terms on the ISS space station have to be supported like infirm patients from a nursing home when they first leave their landing capsule.

Project Longevity (continued 02)

So, to recapitulate: to stop, or even reverse, ageing in the sense gerontology defines it (I'm not talking about ever-growing intellectual and spiritual capacities and insights!), one must do a combination of five things (and knowledgeably): 1) (body) weight training and a few other pertinent exercises, 2) stretching, 3) supplement the body with (mainly) herbal products, esp. 'adaptogens', which influence the degeneration-relevant areas of one's physiology in a way that stops degenerative processes that cannot otherwise be delayed, stopped or reversed via any other means, but which Chinese and Indian sages have researched for thousands of years (to which modern pharma is just catching up, see the definition of 'GRAS' above), but which, however, are innocuous and have no side effects nor interactions in that particular dosage and mixture, then choosing 4) the right style of nutrition (not a 'diet' - this is not about denying yourself the sensual and aesthetic experience of sophisticated fine dining!), food though, that goes hand in hand with the aforesaid resources, and then, last, but not least, 5) adequate sleep (sound, in a quiet and dark environment -sleeping with your lights on will, among other things, cause cancer in the long run- and to memorise things that you learned or that happened to you during your waking state can only be 'filed' in long-term memory, if you allow certain dream phases to occur during your nightly sleep; though I've heard, that abundant and fulfilling sexual activity makes for sound sleep ... Add to this something you should not do: 6) drugs, tobacco, alcohol (in excessive amounts or regularly in even small amounts - if you should require a 'nightcap' to go to sleep every evening, you by definition actually are an alcoholic!) and also no psycho- or neurotropic pharmaceuticals (this actually starts with 'innocuous' things like acetylsalicylic acid, Ibuprofen or Paracetamol, if taken as a matter of course, then you can step that up with Valium, Prozac, Opioids and a host of other substances no one needs if they lead a healthy life, with the exception of some manics and depressives, and bedridden pain patients under certain circumstances which are much, much rarer than statistics of prescribed medinines would make you think).
I know, it's been a long journey to get to this paragraph in my profile, yet still, I haven't drafted this to appeal to the sapiosexual only, but to provide you with tangible reasons to decide for or against applying, esp. if you are more of the 'let's get physical' type.
One last pointer: I won't contact everyone just all over the map to show off my profile, but I will visit many female profiles in search of what I have delineated above. I might not be able to write to all of you, esp. if this should be neither a one-liner nor a copy-paste activity that does no one justice. So, apart from just being too busy (unlike some others, I do have a life outside Collarspace), if I have visited your profile (as you would see in your history), but not contacted you, this could have any of these (exemplary) reasons: a) I looked at your huge friends list and decided you were favouring a more promiscuous lifestyle than I would wish you had, b) I looked at your interests list and either found it empty or I got the feeling that based on your hard limits and/or favourites we could never be a reasonable match, c) your profile is empty or completely vacuous which acts as a deterrence for me, or d) I may have erroneously mistaken you for a scammer because I spotted several criteria that led me to such a conclusion … and, of course, since switches, subs and slaves all have pink nicknames on Collarspace, e) you could be a switch whom I gave a click unwittingly (same goes for subs that have made it abundantly clear they don't even have the slightest slave tendencies).

Should you still, after reading my profile thoroughly, still have a different, more optimistic, impression, you may of course still contact me.

If time allows, I will try and get back to everyone who has written politely (and reasonably rich in substance) within a decent time-span (and in chronological order of receipts), so no need to keep repeating your request for at least the next 72 hours.

Now it's up to you to write back or move on. Even if you decide to pass this over, I hope the study was worth your while. Once again: I am quite good at detecting scammers after a decade or so on collarme/collarspace (in fact I was, and still occasionally am, active in the industrial counter-espionage and deterrence of social engineering domains), albeit watching from the sidelines mainly. I trust that if you're serious, you would reciprocate by not just sending a one-liner but something more substantial that allows me to gauge whether you have read, have understood, and whether you agree or disagree with, this treatise, and to which extent. Looking forward to hearing from the right applicants soon.
