I'm emotionally about 14, according to the wife.
In dog years I'm about ... sheesh I dunno but it's in the hundreds.
When I first wake up in the morning and all my various old race crash aches, surgeries and miscellaneous sports injuries are yelling, "Hey doofus, remember me, HAHAAHAA," then I'm about 90 or so.
On the calendar, it's like the previous poster... a ripping spry ubermale specimen of ladyheart-melting magic at 57.
First ride was age 10. Got my permit at 15.5. ... Have ridden as close to every day as possible since then.
I think a tougher question for all of us more... "experienced" riders would be, "HOW MANY MILES HAVE YOU RIDDEN IN YOUR LIFETIME SO FAR?"
