Ate himself to death.
Exactly. This guy could have taken charge of his life and with sensible care would have been fine. It all boils down to diet and exercise. I have Type II and I am on a low carb/no carb diet and I am now walking 3.5 miles a day six days a week. That is what you have to do.
This guy probably did nothing to help himself and totally depended on a ever increasing regimen of drugs and dosages to live.
So instead of talking care of himself he did nothing and allowed his disease to progress to the point where he was. So for him he choose death rather than admit his own responsibility for his predicament.
Since he had it since childhood he certainly had type 1. It is an auto Immune disease and has nothing to do with eating. At age 68, he was indeed fortunate to have survived as long as he did. He had already had one amputation and all of his organs were failing. Not sure I wouldn’t choose the same in his shoes. Self righteous ignorance suits you well apparently.
