Riding Solo
Well not stupid but the only time I hurt my back was 2 years ago. I got out of bed and it went on me. Never got better although it no longer is so painful that I can't do anything I want. But I only have to bend at the waist to be reminded that it's still there. Hence I've been really careful when I got back to the gym and generally stuck with machines rather than free weights. At slightly over 2/3 of a century it's all going downhill anyways. On the plus side I did manage to slam into a car door on my bike without any significant injury a couple of weeks ago
