Rethinking time

All our lives are ruled by time and it's a fundamental part of our daily routines but what if we could make time go more slowly - or quickly? Adrian Bejan, a professor in thermodynamics at Duke University says that this is possible if we just open our minds to how we perceive change. And if we could make time last longer, what would be the most efficient way of using it? We get some tips from Laura Vanderkam a writer and speaker on time management. Plus, research scientist Christian Clot tells us about an experiment where all markers of time were taken away, including clocks, watches and sunlight - and what that could mean for how we live in the future. And casino designer and consultant, Bill Friedman explains how the idea of timelessness is put to practical use in casinos where professional gamblers want to feel that they're always in the moment.
