Asking me? I wouldn't have a clue how much damage he did to his vertebrae.
I can tell you I smashed my elbow radials and snapped a wrist by falling 4 meres onto a concrete slab.. 5 days of unconsciousness and back to work two daze later with both arms strapped to my torso. But I'm a manly man, the essence of Australian flesh and bone, a legend in my own lunchtime. Jaws crew has nuthin' on me.
