Shame that is truly tragic :( I had a friend who was in a car accident on the way back from a river rafting adventure. He was not wearing his safety belt and was thrown out of the car. He was paralysed from the waist down, but he was determined that he would walk again. He pushed himself hectically for over a year and was able to walk again but then he got some spinal infection and that all went down the tubes and he went back into a wheel chair. So very sad, because after that... he lost all hope and motivation.
Good idea re. the will. I don't even have one... oops :D
