You can't dscount the longetivity in W's family. I mean, his mother, Barbara, looked 100 when she was 50, and his father does look his age, but they're both still here and in seemingly good health.
Do you remember that great late 80s SNL skit when Phil Hartman played Barbara Bush? It was a "60 Minutes" satire where the interviewer asked if Barbara was proud of her son, George H. Bush (a/k/a Bush 41) in a great poke at how old she looked. Hartman kind of flushed with embarrassment and said "George isn't my son, he's my husband."
