I’ve done a lot of research on these people.  This man was a couch potato.  Depressed by the situation with his son, he hardly got out or got any exercise.  After a doctor appointment he was told he needed to get more active so he took his paraplegic son on a walk in his wheelchair.  Apparently his son told him that when he was out moving with his Dad, he didn’t feel like an invalid.  Look what Dad then did.  Get the tissue.
