Have read a few books about him and generally he is as close to superman in mortal form as you can get - absolutely nails ex-SAS.
In the Top Gear interview he very calmly talks about having to cut his own fingers off etc - the best bit is when some locals in his barracks village complained of a film company setting up in the village centre and generally making a mess of it, lots of noise etc - so he went and signed for some explosives and blew the set up.
...despite incredible intelligence he actually lost his first car, was in germany or something and parked it, got drunk, couldnt remember where it was parked the next day and never found it again
