He has the world’s best medical care and orthopedic care available to him. His body has been wearing out. That can happen to the elderly no matter if they are very active as long as possible. Hip joints, knee joints, feet etc. There is actual wear & tear on these areas that keep us mobile which in some individuals can almost cripple them.
As active as this man was, loving golf especially, and even wanting to sky dive, I have to reason that he is one of those whose body wearing out preceeded the segway use. There is just so much surgery and implants etc that an old person can take. My parents were in very good shape and did not have the problems of body mechanics going to heck, but they developed other problems that led to their deaths at 87 for my dad (cancer) and 86 for my mom (dementia, & head injury from falling). So, this stuff happens. It just varies as to the specifics for each individual.
I had a friend, now deceased, who became disabled because of a hip joint wearing out when he was in his 50s. Surgeon said it was the worst case he’d seen...joint not just worn but obliterated. The surgery and implant did not go well. He struggled through it all, trying to get better and get back to work. He had complications from other conditions as well, and he died at 53.
I don’t know what else to say.
GHWB reportedly has a form of Parkinsons that effects the lower extremities, necessitating the regular & public use of segways/wheelchairs/other within the last year.
Like you I have to reason that he is one of those whose body wearing out preceeded the segway use because of his age and especially because noone what injuries he may have gotten from the war. I don’t know a lot about his military experience but I do believe he went down in a plane. Anyways, whether it’s a crash in a plane or a broken arm from a bike fall when you’re young, they tend to come back and haunt us in later years.
What you say makes a lot of sense
