I donated blood today for the first time, at the Red Cross centre in Perth. It was pretty much painless; the tiny stab-sample that Nicole took for testing hurt more than the needle proper, and it was all over (insertion to withdrawal) in under ten minutes.
In three months, I can do it again, and at that point I qualify to be hooked up to the fabulous platelet machine every 2-4 weeks. This draws a sample, centrifuges it, pulls out the platelets and plasma, and then puts the rest back in — so no loss of iron and so forth. Meanwhile, your heart will have been busy circulating stuff, so the next sample is almost 100% fresh.
If a fat old bugger like me can survive this, maybe you can too?
Judging by Jeff’s blog, he came within a whisker of needing some replacement circulatory fluid today — maybe you’re next? <G/D/R>
