My dear sweet sister, Patty, had brain cancer and she was very heavy. She loved to eat ice cream and chips like most but she found happiness in her last days eating those. Her family had her committed to a county hospital and we were told she had 6 months to live.
She was so depressed there with no phone and no contact with anyone and no money for her loved treats so I imagine. She quit eating and was dead 3 days later.
