they must just pull the bits they need out. for donating whole blood you usally have to wait 8 weeks between so 1000 times would be about 154 years.

you can donate plasma every 2 weeks, so 1000 times would be 39 years. if he started at 18 he'd be 57 now. Which looks like it could be right. Fucking impressive.
