There is no age limit for getting a tattoo.*
*or almost… 18 years minimum or else you need the agreement of a parent, I remind you in this article.
The skin is not necessarily more "wrinkled".
It's not necessarily a "whim". synonymous with an existential crisis related to your age.
You have the wisdom of a well-considered choice (article on the importance of carefully considering your tattoo project here).
You are sometimes much more resistant to pain (article on tattoo-related pain here).
I'm not trying toconvince you, only to tell you that:
If a tattoo is really what you want, age is not an excuse, find another one!
For your information, my "oldest" client got her first tattoo at 73 years old.
