When I wrote that book I was asked to justify my comments many times. Serving here with me in mobility troop I have a bloke who broke his leg in 67 places during the fan dance. He made himself a cast out of mud, hardened it over a hexy cooker and tabbed 79 miles back to Stirling Lines. He failed selection because a few weeks later he cut his own head off with a can opener. He didnt fail because of that, he failed because he sewed it on back to front and ended up running over a cliff. Thankfully he passed selection the following year, having got through it with only minor injuries.
