Max Angle: Sorry to say it, but, I've flown with a lot of younger aged felllow pilots whom have had a wink or two, well before 'top of descent'!!!! It's all very relative but, to limit people on the assumption that age is a limiting factor to their abilities in carying out their profession is daft. It's more to do with Unions and the 'labour agreements', drafted and agreed upon to support and promote professionals within the companies. Let's be fair this regulation on 'age limitation' is long overdew for a change.
