Our own devices

by Edward Tenner

From the author of Why Things Bite Back-- which introduced us to the revenge antics of technology--Our Own Devices is a wonderfully revealing look at the inventions of everyday things that protect us, position us, or enhance our performance. In helping and hurting us, these body technologies have produced consequences that their makers never intended:- In postwar Japan traditional sandals gave way to Western-style shoes because they were considered marks of a higher standard of living, but they seriously increased the rate of fungal foot ailments.- Reclining chairs, originally promoted for healthful brief relaxation, became symbols of the sedentary life and obesity.- A keyboard that made the piano easier to learn failed in the marketplace mainly because professional pianists believed difficult passages needed to stay difficult.- Helmets, reintroduced during the carnage of World War I, saved the lives of countless civilian miners, construction workers, and, more recently, bicyclists.Onc
