About a week later I called Jim at home. Sara answered.  She seemed upset.  It was Jim.  He was not achieving normal sugar levels, and they had had to take him back to the hospital. He was not doing well at all.  Sara was just heading back there. I asked if there was anything I could do.  She said that there was not.  She said that I could come up and visit later today or tomorrow.  I told her that I would be there tomorrow, unless something bad was happening.  I made Sara promise to call me.   I remember Jim talking about his grandfather and the problems that he had with his health.  He eventually lost both his legs and went blind, but that was before diabetes was totally understood.  For him, Jim's grandfather, diabetes was a tragedy.  Had his grandfather been born just a little later he would have been able to get proper treatment and would not have suffered the way he did.  Jim was determined not to end up in that kind of condition, but sometimes things get out of control, though no fault of your own.  This is exactly what happened.  Jim had always watched his diet, had exercised, and had monitored his blood sugar.
