I have absolutely no bruise from giving blood yesterday! Every other time I've given blood (admittedly not much) or had blood drawn I've been left with a significant bruise. But I have none! Just a little scab over where the needle was. I'm so happy - I may even have to write to MI Blood & sing Matt's praises.
I did learn a few things while I was there. Warm/room temperature water helps the blood flow better or quicker. Also that my main vein in my arm(s) is a lot deeper than would be expected (have to remember that in school & future blood drives). It took about 16 minutes to get a pint - but for whatever reason it seems to take a little while to a pint.
