Happened to a guy at work. Early forties, physics PhD Cornell, family, everything to live for. Went in for gastric surgery, they nicked a vein, and he never recovered.
A woman friend I know was so insistent on her husband getting medical screening tests for health. He has a gastric scope and somehow they clipped a blood vessel. After the procedure in the bed he told her he felt extremely dizzy and passed out and then away. What a shame as they were expecting many years of enjoying retirement. Message to self-— avoid the hospital if at all possible.
About 100,000 people a year die of things they didn’t go into the hospital for.
My motto is never make a conscious choice to go into a hospital. If i need emergency surgery i am already at big risk of dying. No other time am i setting foot in there.
