I'm 68, going on 69. Forty-eight years ago I was paralyzed from the waist down. Ten years after that I started riding again. When my back couldn't handle an upright bike, I got my first recumbent. Three years later I got a faster one. In 2014 I switched to a Lightning Cycle Dynamics P-38. In spite of other serious medical problems I'm still riding, and plan to keep riding until I die, because I'd rather be dead than not ride.
Pain is the universe telling you that you are not dead—yet.

Forty eight years ago, you were paralyzed from the waist down? Ten years later you started riding, so, you made a recovery from being paralyzed? If I read this right, CONGRATULATIONS!
