I know some tattoos that can be a bit embarrassing to look at, but I don't really think they're that bad. People normally get tattoos as images of things that mean a lot to them, and to express that meaningfulness to the world. While most won't get it, it's very important to the person who has it. It can also be about honoring someone or something and can be even a part of a person's culture! The only "sign of the times that we live in" thing about it that I can think of is that we live in a period when people can do what they like and be who they want to be: themselves. I personally don't think I'll ever get a tattoo, but I find them a really interesting thing in our world.
