I did a century on Saturday, the first one in 14 years. On the ride, I met a guy who was a paraplegic and pedaling with his arms on a specially made bike. I spoke at-length with him and what I learned was this:
We all age and go through the process of our bodies becoming not what they once were - that we cannot control no matter what shape we are in. But our head need not follow the same path. As long as we can get on and spin to any degree, our minds have the capacity to create the enjoyment.
