I never learned to roll back my foreskin when I was a wee lad and so once when I was 8 it got infected and I had to apply ointment to it and keep gradually peeling it back from its swollen and cemented position like trying to squeeze a tennis ball out of a tight gym sock. it hurt to pee for a week. Still, Im glad to have my foreskin.
My plan, if I live old enough to be facing debilitating age-related illness is to organize all my assets to be distributed beforehand, then hike out into the middle of a dense forest where I cant possibly be found, dig a shallow pit to lie in, and die there by whatever means tickles me at the time.
There are no large predators where I live, so Id just be slowly dissected by the ants and the beetles.
