I think this is why it's cool that the OP who will be 40 is getting one (maybe). When you're 18, you're impulsive and rebellious. at 40, not so much. Plus, you probably have your career, your wedding photos, etc... and I think it may even mean more.
I have 6 tattoos and I really like 3 and a half of them. They all hold great significance to me and I do plan on getting more when the time is right so my legs look complete. As for the ones I don't like so much, it's more the execution than the design. I cheaped out which is NEVER something you do with tattoos. I was lucky enough to have one of my tattoos in a few magazines and the artist is one of the best in the industry currently.
I don't understand why so many people still dislike them so much. I can understand if they're offensive in nature or just plain terrible (wavy lines, poor artistry). The stigma still exists somewhat. The thing is - these days it's not just thugs and convicts who sport tattoos. It doesn't change how a person can perform a job. It doesn't automatically make someone a bad human.
People hang art in their homes. Now days, people put art on their bodies. One of my tattoos for example, is an MC Escher piece. I know people who get amazing portraits of loved ones, or recreations of famous art pieces. It is something that lasts longer than a photo.
example:
Sorry for the rant but I'm getting tired of generalized negative statements about tattoos. It's like a kid who has never tried an onion but who automatically hates onions because they're "icky". No real good reason.
