Just get yourself better mate-know what you mean about climbing the walls though. When I was 17 got knocked of my bike, badly smashed left leg just above the ankle(they wanted to amputate it-this was in 1965!) I was in hospital for 5 weeks, healthy and fit as a butchers dog, just smashed up. When they finally let me out of bed and into a wheelchair I broke 3 in 2 days-they had me on crutches and home VERY quickly..........
