hmm, Im 22 and my wii fit age is 16-17, it varies tween the two. When I first started though, it was is the lower 30s, because of my sense of posture issues. (I blame my posture issues on the fact that I am freakishly tall. And I have read in a science journal a few years back about how being really tall can cause quite a few problems when it comes to posture among many other things, simply because everything is designed for everyone or average height or lower.) Regular balance and stuff I have always done good with, I have done VERY dangerous stuff like balancing on bridge rails out of boredom already, and said bridge is over a 250 foot drop.
