It's possible that an injury at age 20 may have started this. He fell a
story and a half, landing on his feet, breaking both heels and both ankles.
His entire skeletal system was jarred. He was in the hospital for a long
time. I suspect that previous alcohol abuse was probably a major factor in
the development of this bone disease, as well.
