Ooh, a thorny subject!
I'm in my 60's now, but had my first ink about 20 years ago, with the encouragement of my daughter, who has a couple herself. It's a small Taoist symbol on my thigh.
I recently had 2 more tat's, but this time on my hands. They are (I think) quite tasteful - tiny pawprints and ? for my belived dogs, and a very small Christian cross. I love them and they both have great significance and meaning to my life.
However, same daughter (who even took me for my original one), has been most disapproving! "Mother!!!! Are you having a midlife crisis or something????" Really surprised me a bit - but also made me hoot with laughter and threaten to get a whole sleeve done!
She can gripe about them all she likes - I'm really happy I have them!
If you want ideas there are thousands on Pinterest, and you can search for specific styles.
Beware of addiction though, I can see how that happens!
