I was soon discharged from the rehab center and sent back to the SAS. But the doctor's professional opinion was that I shouldn't military parachute again. It was too risky. One dodgy landing, at night, in full kit, and my patched-up spine could crumple. He didn't even mention the long route marches carrying huge weights on our backs. Every SF soldier knows that a weak back is not a good opener for life in an SAS squadron. It is also a cliche just how many SAS soldiers' backs and knees are plated and pinned together, after years of marches and jumps.
