is one of his legs 10 cm shorter 
Iggy Pop said....."I have a dislocated shoulder.
I have a lot of cartilage lost in my right hip. Both knees are about to go.
I have one leg about an inch and a half shorter than the other.
When I was thirteen, I was run over by a big guy playing junior high football, and the right leg ended up a quarter-inch shorter.
By my mid twenties, it was a half-inch.
Then in the Eighties, I had no money and was taking packed economy flights everywhere, night after night.
Then in the 2000s i met Tbombz.
The combination of that schedule and a fall I took dancing on an amplifier left me with my spine twisted and a slight limp."
