At the risk of being compared to ‘Jef’ …. I had a cycling accident recently. I somersaulted over another cyclist who had fallen in front of me at my local velodrome. I landed flat on my back and slid 25 feet down the track. I got checked out at the ER, I didn’t break anything or have a concussion but I was pretty sore for a week. I’m 65.
In my case it was ‘track rash’ and only a little on my left arm.
