Concur there chaps. I have been 12 years in a wheelchair ever since a recreational accident left me paraplegic (thorax vertebrae lesion), this guy appears to be tetra or quadplegic (cervical vertinbrae lesion) judging by the photos, and my heart goes out to the bloke.
The main issue is that when faced with such challenges, you have to decide how you want to move on. Personally I adopted the 'crack-on' stance and although it's tough sometimes, I still get up at 05:00 daily to do a 40+ hour week, drive a car, fly a converted Warrior. Horses for courses I guess, but from the 200 plus similarly affected I know, I can count the number that do likewise on two hands and maybe a numb foot.
My tip lad, take a look at what's left, develop what's there, look people directly in the eye, and never dwell on what was. Eyes front mate, it's the only way forward.
