Microlives: the key to living longer and more healthily? | The Guardian

Are microlives the key to living longer and enjoying better health? The basic idea is that a microlife is half an hour. Smoking 20 cigarettes a day will cost you 10 microlives. On the other hand, exercising for 20 minutes on any given day will you buy 2 microlives, and so on. Michael Blastland and Professor David Spiegelhalter have written a book about it, The Norm Chronicles.
