IMHO, sole age is not a valid parameter for forcing people to stop working! There are many old people able to work and many younger people simply unable to ... In the aviation business we do have all we need to overcome the bull**** regulations, so why don‘t we use it? We have checkflights and we have medicals, so if both is ok and somebody wants to continue, why not?
I envy people able to live on the sole expense of others in distribution systems, like the German, but I am mentally unable to rip the younger ones off their wallets.
