If you would think that the oldest tattoo in the world would have to be on an old person, you’d be right. How old exactly? Well, he would be 7000 years old, give or take a few hundred years. His name is Otzi, and he was discovered trapped in a glacier in 1991. He didn’t get stuck in a glacier in 1990, he got stuck in a glacier nearly 1000 years before the Egyptians started building the Great Pyramids.
