He was very, very sick as a child, spending months on end in the hospital. At one point he was in a coma for awhile and almost died. (I don't remember what his illnesses were.) Also, he's allergic to various foods. As a result, he's learned how to take care of himself through the years in ways most other people haven't had to. I'd say he looks pretty good for 79. When he remembers his childhood, I'm sure he appreciates having lived so long.I saw those but I don’t believe he’s 79 in any of them. Really, does he look 79 to you?
