I gave blood for my second time today. Once again, they determined that there are no veins in my left arm that are of use to them. So once again, my right arm, the arm I actually need to use, is achy. I look a bit like a junkie, I think, now that the bandage has been removed and the iodine has been washed off. All that's there is a red mark and a slowly growing bruise, accompanied by a dull ache.

On a somewhat related note: when washing off the iodine, which is yellowish on my arm, I looked at the paper towel I was using. It was turning bluish black. Anyone know what that is, why the color changes like that?

Not much else to say. Time to do work so that I can sleep. Yay sleep.
