O sh..... moments resulting in injuries that I can still remember because they took a long time to recover from or resulted in permanent weaknesses? Let’s see.
A severely twisted left ankle from a biking accident in my teens, probably aggravated by playing field hockey again too soon. Result, permanent weakness.
A fibula that popped out at the knee joint when I got up from a cross legged position (think twisting squats) after having worked under my car in winter. Two weeks on crutches the first time it happened. Nowadays, I know how to protect it and it will take only a couple of days of hobbling around after it happens.
A severely injured left shoulder from a biking fall that was a pure accident. My wife and two daughters had gone ahead with the car to Hanover NH (from just North of Boston). I was following on my racing bike and cruising along at 50 km/hr on a long down hill (sunny spring day, no wind, perfect asphalt, singing a song). My front wheel hit the one and only (1â€) pebble that had decided to be there just for me. I went flying over the handle bars on my head (good helmet) and left shoulder which took the main impact. Dislocated? Maybe. It must have popped back, though, because I still could move my arm a bit. I must have looked terrible (torn bike shirt, bloody shoulder from road burn, white face), judging by the looks of the people in the diner where I stopped half an hour later to have a cup of coffee. Anyhow, I managed the remaining 140 km (I can still visualize sections of that ride; pain apparently does that to your memory). And spent a lot of years getting my shoulder strength and mobility back. With F1, I have noticed that there is still a distinct difference in ROM between left and right shoulder, for example with windmills. In a handstand I can open my right shoulder, but not (yet) my left. My shoulder dislocates look very strange. But otherwise I am fine. Could have been much worse.
A right thumb that dislocated with a downhill skiing fall. Just being stupid and trying to keep up with a colleague who later (of course) told me that he had been a ski instructor. No more finger push ups.
Six years ago, the loss of the use of one of my (biceps) muscles in my right arm with a climbing accident. I had injured (one of) my right biceps lifting a heavy weight (a boat) while cold. But instead of giving it time to heal, I kept climbing. And then on a climbing trip (far from any hospital) while climbing down a fixed rope hand over hand, I felt a sharp pain and that was it. No more one arm chins. Surprisingly, I am still quite strong in my right arm.
With hind sight, though, the worst that I did to my body was joining the long slow distance craze in the eighties. All those miles (up to 50 miles a week) of taking short strides on hard pavement made me stiff like a plank and caused all sorts of joint and tendon problems that I have now finally recovered from.
