Damn, I feel bad for people passing out. I pass out every time I have blood drawn, not from getting tattooed yet, but I'm sure I will at some point. A lot of people who pass out kinda look like they might be having a mild seizure, but in reality it's just the electricity turning back on. I had to go for a brain scan and some testing after the first time it happened to me and that's what the neurologist told me. last time I passed out I bit my tongue, nothing major, just a small bite.
