joy!
I've just been told I've got a very strong heart, and I attribute that to riding my bike. I've battled back from cancer three times, twice enduring a grueling chemo regimen that weakened my heart. But 4 years ago I got a bike. When my family doctor heard me say I'm going to get up to a 50 mile ride this year (I'm 71 and on a Townie), he sent me over to a cardiologist just to make sure...
And so. If it's possible to love cycling more than I already do, then, well, I do. 50 miles, eh? Wonder how much more I can do next year! Ha!
