I have met people in their sixties who know jack shit.
I also have a friend who is all of 26 who knows more about Scotch than anyone I have ever met. And I work in BARS!
Some of the best magicians I have ever seen were very young for their talent level. (If you ever get a chance to see Joshua Jay, take it.)
My friend FE had his SECOND magic bar by the time he was 24. He's been at that one for the last 9.5 years. (I am filling in for him this week.

) He also ran for Mayor of Key West when he was 24.
I ran for Mayor of Tempe, Arizona (my home town) when I was 21. When people would question my lack of experience, I would point out to them that the people with the experience were the ones that had made such a mess of things in the first place.
