Future Perfect

SO OFTEN conventional “wisdom” actually ends up being wrong, or even dangerous! Consider the plight of the mountain-climber who seeks to "bag" one of the "eight thousanders." All her mountain-climbing life she has been hearing the conventional ““wisdom”” that she must move slowly and cautiously as she approaches the "death zone," or else the cognitive, muscular, and digestive ill-effects of breathing air at only one-third sea-level pressure will result in careless errors, rapid exhaustion, and even unconsciousness. PRECISELY THE CONTRARY IS THE CASE! Instead, she ought to move faster than usual--about 300 m.p.h.--with her mouth wide-open, thereby force-compressing the air to 15 p.s.i. as it flows into her trachea, a process reminiscent of that within a jet engine.
