'Our Own Devices': Smothered by Invention
By DAVID POGUE

In his eye-opening ''Why Things Bite Back,'' Edward Tenner, then a
visiting scholar at Princeton University, vividly illustrated how a
technological advance can unleash unexpected consequences. For example,
the wide distribution of antibiotics has led to resistant bacteria; neck
and spine injuries tripled after the debut of football helmets; and
computer keyboards triggered an epidemic of wrist ailments.
In ''Our Own Devices,'' Tenner -- who is now a senior research associate
on invention and innovation at the National Museum of American History
-- presents loosely connected historical essays on certain examples of
what he calls body technologies, many of which he touched on in his
earlier book: baby formula, sandals, sneakers, office chairs, reclining
chairs, piano keyboards, computer keyboards, eyeglasses and helmets.
