There was a blood drive in our town last week. I missed it once again because of my present work, sleep, work, sleep, work schedule. Motivated partly by the Ft. Hood terrorist incident, Sara Jean went to donate. Coincidentally on the way to work that night I heard a blurb on the radio about problems you might have donating blood at some facilities if you have "skin art".
I was listening to a distant AM radio station and static precluded me from hearing much of what I wanted to hear.
The straight skinny on tattoos and blood donation can be found here.
