Scientists in Korea claim to have data indicating that the lifespan of Eunuchs was significantly longer than un-altered males in times past. They found unusually numerous reports of centenarians existing among the castrated men centuries ago. They could not attribute the longevity to the rarified existence among the royals of Korea, since the kings and their family members did not share this benefit of long life.
The scientists suggested that testosterone might be the culprit that shortens men’s lives. It’s a POISON! 😉
