well I am 33 and had mine taken out on Dec 4th of last year.
I actually had 6 wisdom teeth compared to the normal six!
They didn't bother me for awhile but eventually a couple had cavities or were about to so I had them finally taken out.
I was knocked out for the surgery. I took a couple days off work and watched movies and tv shoes like MOTU lol.
I am glad I have them out and wish I would have done it when I was younger, and under my parents insurance so they would have had to pay.
Even then I am glad I finally did it.
