The Staircase

33 sources0 graded recommendations

Published Updated

In 1966, five healthy young men in Dallas spent three weeks in bed. When they got up, they had lost more aerobic fitness than the next three decades of aging would take from them.12

Nothing had been done to them. Something had been taken away: the daily signal that a body is being used. Take away a signal and the system that reads it drifts, fast. Restore it and the system answers, often within weeks.
