I had a jaw deformity, which didn't get corrected until I was an adult. (Had I not been so socially withdrawn, I might have gone to a better school when I was younger.) By the time my condition was treated, years past the time most of my peers would have started families, it was too late: I had become used to having time to work on my own projects, and having to get up every day to do the kind of unfulfilling work fathers typically have to do to provide for a family would have been intollerable. I was spared.
