Ashcroft's book is a thoroughly engaging survey of those limits and their origins in the nature of things, of what happens to human beings in the most difficult environmental conditions. She writes, for instance, of why it is that astronauts have trouble standing after returning to Earth (because, in part, their leg muscles quickly atrophy outside of terrestrial gravity); of how the famed Japanese pearl divers condition themselves to attain such extraordinary underwater depths; of how and why the consumption of carbohydrates and caffeine can improve athletic performance; of why British children so easily suffer heat exhaustion on trips to such semitropical venues as, say, Disneyworld, whereas young Saudis can tolerate much higher temperatures (but would likely not thrive in an English winter).
Backed by extensive field research--the author has climbed Mount Kilimanjaro, sweated it out in Japanese hot tubs, and run after her share of buses--as well as by a wealth of laboratory studies, Ashcroft's book is of great appeal to anyone who wishes to test the world's limits--or their own. --Gregory McNamee --This text refers to an out of print or unavailable edition of this title.
I read her most recent book first (2012) and did not reach much of this. Not in depth enough, I was looking for more science.Published 18 months ago by aa
