if you scroll down, there is a picture of this person. He is now around 58, no "children" mentioned, either.
Interesting pic:
He has a Coast Guard flag (or banner) in the background. If he's a late 50-something, he couldn't have served in Vietnam. I'm not at all diminishing USCG service, just pointing out a chronological fact.
The book he has and his sourcemage.org page indicate that he does software, a career field unlikely to be affected by many/most disabilities.
If he's in his mid-late 50s, the most prominent aspect of his appearance suggests a Peter-Pan-like
never-grew-up,
because-I-still-can mindset (I can't, but am mature enough never to have cared that the top of my head is not hirsute).
