I gave blood today. No big deal, I should do it more frequently actually. Well I was interested and Goggled Is giving blood good for you? I don't know why I never thought about that before. Mostly just good for others.
Well it turns out it isn't good for you, it is GREAT FOR YOU.
Especially if you are a man. I mean really freaking great. Very good at helping prevent heat attacks. So get going and donate...for others AND for you.
