David Spiegelhalter, a statistician at the University of Cambridge, has devised a novel way of weighing the benefits of one health resolution against another, using the concept of ‘microlives’. Instead of measuring habits such as red meat consumption in years lost from the average life, he calculates the effects of daily choices in small units of time, called microlives.
Spiegelhalter divided up the years remaining for a 35-year-old with a typical life span of 80 years into nearly a million 30-minute periods and defined each half-hour as one microlife. He then calculated how various habits may affect the microlives a person has left.
It isn’t hard to lose a microlife. Averaged over a lifetime, habits such as smoking two cigarettes, eating a burger, keeping 11 pounds overweight, watching two hours of television or drinking a second or third alcoholic beverage each result in the loss of one microlife.
So how much time have you lost our gained today? We have created an online calculator to help you work it out:
