in my opinion, and my opinion only after years of surrounding myself in this subject - sex is; and should be considered - a benchmark of all things health related.
And therefore from what I've gathered, yes, whilst it is still important to maintain those 75kg bench pressing regimes, but at the end of it all - there is just nothing else I would find that would be in a form of a "test" that simply in itself - "test" of how we both enjoy (pleasure, intimacy) and endure (strength, virility, endurance) life..
I'd like to call sex simply as a test; of all 'tests'. Because whilst sure I am no doctor - but logic prevails especially from a personal experience once you put all things into one, single, whole perspective - no matter if whether you are interested in the biology of things (physics and science) or simply just in the mind-over-matter of things (psychology, beliefs) - regardless to me there is just simply nothing else in the whole wide world that doesn't justify sex as a hidden, underlying aspect of almost everything we live for.
In other words, everything we live for; is all comes down how we relate and connect to one another in a simple, yet highly complex act that there is simply nothing else can compare to it. Because for a simple reason, there is just nothing like it.

Let's see within each and every bedroom acts, it :
- tests the strength, and endurance for all muscular groups; obviously. Especially within the legs. If you google enough research, the legs are; generally speaking - where primarily the most abundant "sex" hormone testosterone are produced.
- tests the effectiveness, and health of nearly all of organic / bodily systems, especially in the moment/s of it; besides especially just reproductive system (respiratory, circulatory, nervous, muscular, skeletal, and yes - including digestive)
- in the event/s of anticipation before the moment/s of it, ie. the 'outer-course' or simply 'foreplay' - it tests nearly all of our organs; and their relative long-term effectiveness (the brain, heart, kidneys, liver; and what I personally believe as the 'secondary brain' - our thyroid gland).
Now, the above are more or less mainly covers the physical aspects of it. Now for the psychological aspects, which is just as important - sex:
- tests your balance for a healthy levels of all neurotransmitters in the brain. Dopamine, serotonin, etc. All of these comes into play. Even cortisol; the negative stress hormone; comes as a factor.
- on the psychological outcomes; it tests your level of overall satisfaction with yourself; whether it be your own values, or belief systems, or simply a way to assess your own level of confidence.
- provides a way, or a method, of- influence & discovery. This could be anything. For anyone out there who has never had sex; again, this could be a discovery of almost so many things. <- this I must say comes very important as per my past history. I never knew I had so many 'problems', physical & mental wise / that I have had to live with ignorance for nearly two decades only until someone else have helped me discover what those were.

So in short, sex is unlike anything else in life that we both live and attest to. Even if it comes as an opportunity ever so sparingly for the disadvantaged or the unpriviledged many - it is still deservedly special because it is simply a way of being 'human'. And unfortunately, not everyone has a "knack" or a "gift" of everything of what they have; either in themselves, their health or their external wealth in delivering and enjoying the acts of it.
