I don't look. I figure I probably don't have issues with it, but why risk finding out?

I like giving plasma or platelets, because they'll put back about 70% of the volume you've lost as saline, and the one time I almost passed out, it was because of insufficient volume in my blood vessels. Of course it takes longer, and with platelets you have both arms tied down, but it's much easier to deal with.

That reminds me, I need to reschedule platelet donation *again* because I didn't realize the Sunday I scheduled for was Mother's Day.
