That really sucks. I know of a particular ICAO jurisdiction where a 70+ year old is still flying on single-pilot commercial ops. As long as they meet the Class 1 medical standard, they are good to go.
To me it seems narrow minded to stop someone from flying solely upon reaching a certain age. And what's the logic for age 65, I know of some 40 year olds who dropped dead at the controls following a sudden heart attack.
