Alan had a bit of a physical disability. When he was 12 and 13 he had brain surgery to remove a benign tumour. That's what affected his hearing and why later on he needed cochlear implants. When in the last surgery they removed the tumour, they had to take a little piece of the brain, which affected his right side. He used to write with his right hand; he had to learn how to write with his left hand. His walk, of course, was a bit lumbered because his left leg and his left side just didn't work one hundred per cent, but he had no physical disability.
He could walk down the block. For years, he could walk miles. He had stairs in his house; he could go up and down. He would come down from his bedroom and go into the kitchen. He did all his house cleaning, all his own shopping and all his own banking. My brother would come down and drive him to do those chores. His physical ability didn't limit his living by any means.
