Notice how doctors say "levels are fine for your age" for various hormones. For whatever reason them declining is considered normal so nothing should be done about it. What if you are 60 and want to have the muscle strength, metabolism and/or mental acuity of a 40 year old? Turns out, it's possible! You just use the same hormones (or analogues) from external sources. The downside seems to be a shorter lifespan, but there's been no major studies on it. However, it makes sense - you push your body harder. I think quality of life:length of life should be left up to the individual. I'm sure many will choose a more active life up to 75-80 years than a slower one up to 90+. My grandparents and their brothers/sisters basically did nothing after 70ish. Just literally waited to die, too bored and/or tired to do anything more. One of my grandfathers just drank for 15 years until he died. My remaining grandmother is 84 and still doing gardenwork, but otherwise she says "eh, I'm ready anytime". Length of life should not be as important as it seems to be today. Quality matters, too, for some people - even more.
