I've been banned from donating blood before, because I ate beef in Britain during one of the mad cow scares.

Neato, I'm not in a country where they pay you to donate blood, it is 100% just a voluntary "nice thing to do" thing. They don't want it? That just saves more blood for myself. No pain, no tiredness, no lightheadedness, no other side-effects, no risks of embolisms or other risks whenever a needle goes in you. Just plusses to not donating blood, really, if the rest of the population is still doing it.

I don't have encephalitis (mad cow disease), I've been checked, but they want to stay safe just in case, and that's just fine with me. Less risk to me, less risk to the future receivers. I don't see why this other group is whining over it, it's just net profit.
