#10 says you get free juice and cookies. True. I also got ice cream today. Birthday cake ice cream tastes like store-bought frosting.

#9 says you'll weigh less. True, but refer to #10. If I give a pint of blood and then get free juice and cookies, am I now one pint lighter? (Pints are volume, by the way. Blood is thicker than water, though not much thicker.) (Cecil adds this comment: 'Americans are so pathetic.')

#3 says blood is something money can't buy, but don't some places pay you 50USD for a plasma donation? It's also just a stupid reason. Who gives a damn about the rich and famous? You get juice and cookies, man! Juice and cookies! Get to it!

So, today I gave blood, and they were all 'Anyone type-B or type-O?' and I was all 'O-neg FTW!' and they were all 'Great, go there' and I did, and I gave double red. Conscription. I'm down with that.

Anyway, because I gave double red, I got a groovy Red Cross baseball hat. So I can wear it and advertise the Red Cross and people will see me wearing my cool hat and think, 'Oh, look, he must be trying to hide the fact that he's going bald' and then they'll think 'OMG, Luca's in chemo!' and I'll be branded a hero, because people with cancer are heroes.
Only, I don't have cancer and I'm not going bald. But I gave blood doubly, so I am a hero. Props to me. I also got cookies.

Anyway, because I gave double red, which means they put the plasma back in, and it was cold. Normally, I'm fine walking around in sub-zero (C) temperatures in short-sleeved shirts, but that's because I'm warm and the outside is cold. Here, outside was meh and inside I had cold blood flowing through my veins. While I 'drank' the ice from my orange juice. So next time I'll dress more warmly.
