I actually have never given blood. I have four tattoos and some facial/body piercings, and I have managed to get them over the entire time period I've been eligible to give blood, pretty much, and the tats and piercings were spaced in such a manner that I haven't been eligible to give blood since I was 18 (which is 5+ years ago at this point). Honestly needles really bother me and I have a tendency to passing out that seems to run in the family (the blood bank actually told my dad not to come back because he passed out every single time he gave blood - they would have to keep him there for an hour or more), but I am willing to try. I am not expectant that giving blood would go well for me, but at some point in my future I am going to do it! (Still have about 6 more months before I'm eligible, though!)
