You guys missed an important point in the story. The man's wife died "over a year ago."
Some people really don't want to go on after their spouse dies but can't commit suicide for religious or personal reasons. So they just stop living. A friend of mine's mom died last year. The woman's husband lasted seven weeks without her. He had plenty of money and all his marbles. At that age, losing the drive to keep going was enough to kill the man.
Unfortunately, some men of the WWII generation cannot cook or fend for themselves domestically. I'm not making a general statement here, I'm saying some men. Perhaps taking on double duty was more than the old man could bear.
If this guy had all his marbles and all that money, I'm saying there's more to the story than an insensitive public utility or an uncaring immediate family.
A couple of months ago, my aunt checked into a hospice and died peacefully three weeks later. Her beloved husband died about 15 years ago and she was fighting a losing battle against her aging body. The last straw was her kidneys failing and the need for dialysis. Despite protests from our family, my aunt made up her mind and checked out. Really, only you can know when you've had enough.
The man lived 93 years. His wife is dead, most of his friends are gone, and his kids are busy with their own families. You and I don't understand but maybe we will when or if we get to live that long.
