In the cities of the rich world no woman is expected to wear a garment until it is wornout. (Men, unaccountably, tend to hold on to their clothes for years, but the industry is working on the problem.)

About 90% of workers at the 50 large and medium-size organizations that have done sensor studies with Dr. Waber's firm agree to don the badges, which are intended to be worn the entire workday. (Bathroom breaks are optional.) Those who opt out can wear a dummy badge, which appears identical but doesn't record or transmit data, he says.
