An arthritic L5/S1 spinal joint, much like my own, except mine has the hardware from the pointless major surgery that did absolutely nothing to alleviate my back pain. On the bright side, I did wind up on massive doses of oxycontin after all else failed. Got tired of that after several years. Now I'm hooked on endorphins. And no trips to the pharmacy. That's what motivates me to ride.

Hell, my dentist gave me a prescription for Tylenol with Codeine after my recent root canal procedure. The paper is in the drawer, I never filled it. I've been taking Aleve.
