So, I’ve got this old scar on my arm from when I was a kid—maybe three cm long and about a cm wide. I decided to get tattooed right over it, and honestly, for the last decade, the ink has settled perfectly fine. It looks just as solid as the rest of my skin. My only weird hiccup was that when the needle hit that specific spot, it actually hurt. The guy doing the work didn't say anything about it being an issue, though. I don't know how much that helps anyone, but I can't stop thinking about whether there's some underlying capillary issue. Then again, if it's just an old scar, why would it even matter? The real nightmare is when you wake up years later, realize you covered yourself in ink, and you're suddenly old and out of shape instead of young and fit. That's why you have to be smart about where you put the ink if you're dead set on it—pick somewhere it won't interfere with your job, or somewhere where your skin isn't going to lose its elasticity and drive you crazy later. And fair warning: once you start, it's easy to get hooked. That's why people end up going way too far.
