I know the stats around life expectancy, but I am finding it mentally hard that so many people I know have died in their fifties and sixties. A few were expected e.g. colleague who was a functional alcoholic, but so many were not expected. A marathon runner who was very fit. A slim and active woman who died of cancer. Another woman who was sporty who died of a rare lung infection. etc etc.
I really do not expect this as I got older. It makes me afraid and makes me worry my partner could die at any time.
