So, I'm a heroine. I gave blood, and I have the sticker -- and the tiny mark on my arm -- to prove it.

See, I have to build myself up like that to actually get to the bloodmobile -- "Do it; it's your chance to be a hero -- or heroine, I guess, since you're a girl," I tell myself as I prepare for the not-incredibly-pleasant experience.

But if you've never donated blood before, don't let that statement deter you: it's really very tolerable. In fact, the most challenging part is trying to look as innocent as possible when you answer honestly that you haven't slept with a man who slept with a man before 1980. I'm telling you, those nurses really try to judge your honesty by your facial expressions.

We had a little bloodmobile team come to the office for a day. With that in mind, the most rewarding part about donating this time -- aside from the juice and cookies and that whole saving-people's-lives thing -- was that my co-workers who also chose to donate praised me so highly. Something like this really sorts out the needle-phobic from the arms-of-steel type. Oh, and it sorts out the world travelers from the rest of us, too.

If you're thinking about donating, I have compiled a short list of tips that will help you survive the ordeal -- and maybe even enjoy it a little.

Read that material they give you. Not only is it required, but it really lets you know how professional they are and that they have all the bases covered. They give you about 17 chances to walk away during that time, if you're not entirely comfortable.
Be brave during the pre-blood-donating tests. They're going to prick your finger and squeeze out a drop. It doesn't hurt, I promise. Don't watch if it makes you queasy.
Don't take it personally if they like one of your arms better than the other. It's really for your own good.
For gosh sakes, look the other way when they come at you with that arm needle. It's not even that scary to watch, but why risk it?
If at all possible, chat with someone. It takes your mind off the slight discomfort and makes the time pass more quickly. Luckily, our bloodmobile was so small that Kevin, the guy who took my blood, had time to keep me company while I drained.
Choose the very best snacks available. I had my choice of several packaged cookies, juices and sodas. Take your time and pick the best they have to offer.
Finally, don't forget to stick on that sticker before you leave. People will really be nicer to you ... if you're not snotty about your new hero/heroine status, that is.

And there you have it -- the blood-donating tutorial from a girl who thinks she's a heroine.
