I knew this man, who only after few weeks of marriage was in a car crash. He became totally paralysed but could still speak and had use of 1 finger and could bend his neck. That was all the movement he had.
I met him around 15 years after his accident and he was telling me what a blessing that it had been. It had allowed him to find talents within himself that would have not happened had he been rushing around, scattered as before.
He was a whiz on the computer, designed web sites for a living and he did all that, just using 1 finger and speeding in his electronic wheelchair. He also had a fantastic curcle of friends and plenty of $$ from his work.
Many people don't have all that he has and they have no apparent physical disabilty (if you want to use that word)
