Bloodletting is therapeutic… for some very specific conditions. For example, hemochromatosis, where the body has too much iron, and there has been some preliminary study that blood donations are a way to reduce the amount of PFAS in blood.
But everyone has PFAS in their blood; not every male has (beyond normal) phimosis.

There’s too much to keep track of these days.
