Well OK if you say so, but that’s probably not the way to bet.
300 pounds, there’s not much quality of life, when simply putting on shoes is an ordeal. (Which they probably don’t, because they ain’t goin’ anywhere anyway.)
My step grandmother was obese, in a wheelchair, partial amputation on one leg, blind, deaf, and prone to confusion. In a nursing home. That ain’t no way to live, and that ain’t no way to die.
I agree about the quality of life, but my grandma bought a 1969 Chevelle new off the lot in Redding CA, and drove to my parents house by herself, she was 73 then. She kept driving and travelling until about 1976, and gave the car to my cousin in Redding. She was happy and healthy, cooked and darned socks, made afghans for fun and family. She was big, but tough. She had various furs and a mink coat given to her by a trapper for feeding him when he was broke. Ran the cookhouse at her families ranch, taught school, and ran the Post Office too. The really fat brothers wife, she lumbered and breathed hard.
