Short answer: 0
Long answer: I always kinda wanted one. My wife and I semi-seriously talked about me doing a sleeve and I had some really cool ideas for it. But I always had a couple of reservations:
• Whatever I like today may not be what I like 10 years from now (more likely than not actually)
• I’ve read too much about ink in lymph nodes
• Police reports always ask for “tattoos or identifying marks.”
