I"m a fairly regular donor (mostly platelets, now).
I totally hate needles and agree wholeheartedly with the "don't look" comments.
I'm big on checking out other folks there, studying lines on the ceiling, whatever it takes.
Hydration is good. I learned (the hard way), DON'T ride your bike home from your blood donation appointment! It's a good day to take a day off from the bike, in fact.
Thanks for donating!!
