I was 23 in '65 a really great time to be young; Elvis, The Beatles, Chuck Berry........
I started riding again in 2000 on my '87 Cannonale MTB and have recently (late last year) started riding road and beginning in December I've begun road racing, yahoooo!!!
I'm absolutely stoked. I have bought a new 10sp GT and I'm going gang busters, training with some young triathletes Saturday mornings and racing Sunday mornings and Monday afternoons. How long has this fun been going on????
I could say, as I did when I started sailing in '86, that I wish I'd started earlier but just how much fun can one person have???
I hope all you 23y'olds have as much fun in your lives as I've had/am having, in mine.
Stay young.
