I am horrified that the regulator (CAA) has the right to regulate my 'dignity'!
How undignified would it be to meet one of the locals in your village, who has always known you to be energetic and active and enjoying your job, who commented that you seem to be at home a lot these days and you had to say that you weren't allowed to work any more as the assumption was that due to your age you might be going gaga and incompetent.
Our vet has a wonderful statement about this: "Age is just a number". The same would logically apply to human animals too.
