..OK, who's over 70 ?? C'mon , be honest and tell everyone about your reaction times, your bad back, your eyes, your concentration abilities, balance, carpal tunnel pain, arthritis, and recent dental work. All the cool things we think about all day.....Me, I ain't too bad, but I do, at times, while riding the Airhead, think that I sure don't want to fall over any more. I have to shake those thoughts off before I start having fun. Any takers ??
