" I would feel lousy at the Roque De Los Muchachos Observatory in La Palma which was at 7,861 feet, and I would have to take company supplied drugs and oxygen to work at the Mauna Kea Observatories (MKO) in Hawaii at 13,796 feet. In both cases we would rapidly ascend to the summit in two hours or less from near sea level. "
