It would explain a thing or two about my health being as good as it is, but that can already be explained away by recessive genes. My dad is the only person in our entire extended family who has any of the health problems he does.
That said, he'd still be my dad, and I'd still look up to him. He's accomplished more with a broken body than I ever will with a whole one...
for which I blame rap music and sex on TV. Also violent videogames.
I do have such a situation in my ancestry, though. No one is sure who my paternal great-grandfather was. My family name is a best guess among three candidates. Frontier sexytimes at the end of the 19th century were apparently kinda crowded. No wonder my granddad joined the army when he was 16. One of the few who didn't get drafted to fight in the pacific. He already had some rank when it kicked off (didn't keep it, though. He was a Staff Sergeant through most of it, but he was discharged as a PFC. My grandfather was a very angry man).
