driving a heavy vehicle has no bearing on flying light aircraft, most flights are 1 to 2 hrs at most, trucks drivers 4 hr stints at night get white line fever, very boring , for me flying keeps me on my toes, always something to do or see especially on the east coast, a blanket approach is not what is needed, other countries do the self medical with out any increase in death or injury, and as most of us older guys/girls fly we tend to be more cautious,
