Disagree.
Mating selects that you are attractive and in good health until the age of 20-30. By that age you have passed on your genes by making children.
If you die immediately afterwards or live in bad health, evolution does not care for that too much.

Of course in social animals it brings benefit to the species if you live another 15 years to help your children grow and surviive So after age 40-50 selection stops anyway.

Maca's effects on human sexuality are less simple than "boosting"; it
appears to improve libido, but has no impact on impotence, for example
(given that this is the primary market for Maca, seems unfair). It is
possible it increases testosterone, but a quick look into Maca after J's
post didn't yield much on anti-aging potential.
There's no contradition between testosterone and oestrogen, contrary to
the popular view that they are in opposition they are important hormones
for both genders.

If Maca works boosting male fertility, it may increase testosterone levels.

-> estrogen activates telomerase (in endothelial cells).
Fun fact: aspirin does too
Is that a contradiction?
