I still have mine...and I'm a shade over 30. Which, I heard is a bit rare.
Anyways, I had them x-rayed due to another tooth issue, and the lower wisdoms are growing sideways, and the upeprs are a bit crooked. None of them ever erupted, nor have they caused any issues.
I've seen a few family members go through the removal, and I don't want any part of that. So, I'm taking a wait-and-see attitude over it.
