and besides that...you can take a sharp 25 year old guy and a 60 year old doing the same test and you will see different results....
so tell me is the 60 year old dude not qualify for flying your family or mine around the country?... because his reaction time got slower by age? even though he has been a captain for 20 years?....
our profession is base in knowledge and also experience...
you cant replace experience...
