This! I got my first tattoo at 28. My husband and I got each other tattoos as wedding gifts...permanent vows, permanent ink. 27 years later we're still married and my tattoos still look pretty good
However, I have no doubt that what I had chosen as a tattoo at 18 would not be something that I would still be happy with now. My tastes changed a lot over the 10 years between 18 and 28, I changed a lot as a person.
My tattoos are on my shoulder blades and are usually covered. I once had an older woman come up to me at the pool and ask what I thought those "pictures" on my back were going to look like when I was her age. I told her that I tried to pick a place that wouldn't sag too much.
