Regardless of legislation, how about recognising one's limitations?
One thing that separates the vast majority of avaition professionals from their equivilant in other trades is the ability to know when enough is enough.
I am not suggesting that Captain Bloggs should retire from their command of a B747 at 60 and never fly again, they obviously have a wealth of experience which could be passed on by other work in the industry, just as many ex - operational atco's go on to become instructors or work in the development of safety and systems.
I only hope that whatever l legislation is passed, we are still allowed to give something back without having to fight our way through layers of red tape and nonsense.
