Today I went and donated blood for the first time in ages. Here I am, living pretty much down the street from a donor clinic, and I'm sure it's been at least a couple of years since I donated. Despite all that, I've made at least 10 donations so far in my life, according to Canadian Blood Services.
I figure I should donate - since I can. The needle pricks a bit, but other than that I'm really not affected by donating blood. One time several years ago I ran all the way to an appointment after donating - there had been a lineup and it took longer than I expected. (I didn't faint. Or really notice any discomfort except a little dampness under the arms!)
Plus, I'm O+, like most other Canadians, which makes me a good donor: anyone who is A+, B+ or O- + can receive my blood.
Most importantly, I once saw someone who'd recently had surgery literally go from ash-grey/barely functional to mildly pink and upbeat after receieving blood. It was amazing.
Incidentally, Japanese people apparently believe that your blood type predicts your personality. According to Wikipedia, I should be ambitious, athletic, robust, self-confident, and a natural leader. (Oh, and Arrogant, vain, insensitive, and ruthless.)
So I guess it comes down to this: I'm superior to anyone who hasn't recently donated, I am confident I will someday get my 50 donations pin, and I will take you to the clinic myself if you need a friend to lead the way. But I might not let you wimp out if we go.
Kidding. But if anyone wants more info, ask! Or see Canadian Blood Services.
