Tattoos

40 or 50 years from now there's going to be an awful lot of saggy, wrinkly geriatrics walking around with inked up arms, backs, ankles, breasts, necks and butts. That'll be a sore sight for eyes. And what will the then young generation think?
Some things I've learned about getting inked:
Never get anyone's name, except maybe your kids. Other people pass in and out of your life.
Make sure the design really means something, at least to you.
After you've come up with a design, think about it for a while. Because you'll own it for a while.
Remember that someday you'll be on a job interview, just in case you don't make it as an artist or musician. So if possible, ink discreetly. Another advantage to discreet placement is the less the ink is exposed to the sun, the less the chance that it will someday morph into an unrecognizable blue blob.
