ha ha ha ha, I don't know if that is true, lol, well, it was brought up tonite at my house, my son was with his friends and one was getting a tat. I reminded him, not to get one, because I could possibly need a bone marrow transplant, and if so, well... I got this great kid, he won't get one. I just wasn't sure how many people here, reading this forum, might not realize if they need a loved one to help them out medically to ask their kids, or loved ones to refrain from piercings and tats.
