Like everyone else I rode as a kid, but didn't start seriously until age 27. College and starting a family got in the way. I was told by doctor to start riding to recover from knee injury. Well I have been riding for 42 years since on a fairly "serious" level, over 216,000 miles. After hip replacement and spinal fusion I am still riding. Currently recovering from spinal fusion of 3 vertebrates in lower back. Rode for the first time this week since surgery. I managed 5 miles today. A long way to go, but at least I am riding.
