Surely age is not the issue. Peoples are living longer, staying more healthy and working longer. ICAO is about to raise retraite to 65. It means that pilot can be more like normal person and have a normal working life. The main issue should be ability to pass medical and OPC, non? When I was flying there were good and bad pilots, but age was not a factor. Some want to finish early and some not. This the same with all jobs, non?
