So does blood donation have an effect on life expectancy?

[Cthulhu_]

It sure does for the recipient!

Probably yes, but it's hard to tease out how much since there's a lot of restrictions on who can donate, so people who donate are already a healthier demographic

If the effect is likely positive, then isn't it in the interest of bloodbanks to find out?
