>>513946285 (OP)it's what's called an 'evolutionary blind-spot'. There is a point where it's not going make much a difference to your descendants whether you live past a certain age. In the case of women they become infertile, men's sex drive decreases with age, and the idea is meant to be that such individuals should be focusing on their children and grandchildren. So it doesn't matter if you die.
Take a more extreme example, something like a condition of mitochondria. Then the baby doesn't develop or there are miscarriages or it dies before it matures to adult (reproductive age). That's the time of thing that's going to be heavily selected out.
Something like some disease where your brain slowly degrades over a period of 10-20 years long after your peak years for having children? Not so much evolutionary pressure there.
There is a lot of crap in the environment, industrial chemicals, heavy metals, these "forever chemicals" that are 100% synthetic that cause health issues.
I remember someone saying it can also be caused by like a retrovirus, like HSV, because during your prime years when your immune system is healthy it can fight off and control infections (and the garbage proteins) but when your immune system and brains ability to flush out this junk declines with age it starts a process like a war of attrition that your body can't win.
At the end of the day, there is the law of entropy. Everything degrades, wears down. Your body has mechanisms not just to repair, but to repair the repair mechanisms. But it's not infinite. That's why during certain times in your life ageing actually accelerates because if the thing that repairs the thing that repairs your DNA is damaged it has a compounding effect.
Basically your "it feels fake and gay to me" feminine approach is wrong and you'll have to present a better argument. There have been many theories over the years. My friend is convinced that people using aluminium to cook everything is another culprit to look into.
