I will never donate blood, because I have a strong fear of needles and other pointy objects which sink under my skin. I'm not killing anyone because someone else will donate blood.
Also, football players are notoriously stupid. Don't believe what they say unless they can either back it up or it's about football.
I played football for ten years, and just sent out my applications to Duke, Dartmouth, BC, and Princeton... got a 2200 on my SAT's as well. That count as backing it up? No hard feelings, just wanted to point out we're not all muscle-bound oafs.
OT: I donate as frequently as possible. I have O Negative blood, so it's needed. I feel no ill effects, and am not afraid of needles, so I have no reason not to.
