Congrats! That kind of news just wants to make you get out and do a little more cycling!

I had a similar experience at the doctor's a few weeks back and I STILL feel good about it (and that after only a summer of cycling not 18 months)

But I got an even better feed back last night: I was with my little 6 year old buddy on a football field when his mom left to get a bat & ball out of the car. He suggested we have a foot race from one end of the field to the other (over a hundred yards) -- and I not only made it, but was not even breathing hard at the end! So, then he wanted to race all the back to where we started -- and I handled that OK too!

I could not have done that 6 months ago. No way, No how!
...(But I was still happy to see mom with the ball and bat so we could stop the racing!)

Cycling has made a difference for me: I'm not only physically in better shape -- but mentally, I feel sharper and clearer...

Keep up the good work!
