I got my first cycling related scar when I was six years old... came off my Mustang and slammed my wrist into the edge of the fender and ended up with a deep cut that encircled almost my entire wrist.
After nearly 40 years that scar is almost gone (it was a vicious injury) and has moved up my arm by about 4 inches...thinking I came pretty close to slitting my wrist there.
I have many scars from wrenching on bikes, the most bizarre injury was being impaled by a strand of brake wire that went right through my thumb... was removing a canti cable clamp and when it flipped open this lone piece of wire shot out and went right through me. It was less fun pulling it out.
Worst injury as an adult was when I landed a 10 foot drop and took a spill coming down on the exposed chain ring... that left me with series of scars that runs from right below my knee to the top of my foot. It required the use of all my first aid supplies to cover it and had it been an inch left or right would have sawed through my calf muscles instead of my shin.
Rupturing the bursa on my left knee when I went down to avoid a head on crash with another rider might be the most painful injury I have ever sustained... compared to that sprains and dislocations are nothing.
At least you can ride with broken ribs.
