K I was thinking that I wanted to have a positive impact on the world and I know theres lots of ways to do that. I was wondering about kidney, blood, bone marrow, etc donation. Could somebody get paid (By an individual or whatever) for donating any of those things? More importantly, what sort of effects would doing any of those things have on my body? (I suppose bloods fairly safe to donate if done in the right amount, etc) I think kidney donation would have a positive impact on the world because it would allow somebody to wait less time than they would ordinarily have to (For a kidney) (Maybe). Ive also read that somebody can be fine with just one kidney and that that one kidney that they have will enlarge, etc to make up for the other missing kidney. I was also wondering, if somebody wanted to help speed up the search in identifying all the genes in the human genome and stuff like that, what could they do to achieve that, as individuals or groups?
