Cherry Healey investigates why people work so hard and play so hard in a world that never switches off. When so many of us are working longer hours than ever before, how are we also partying as if our lives depended on it? And is it really making us happy or just stressed? Cherry meets a man who works 20 hours a day, a group of lads who regularly blow their weekly wages in one night and a single mum who holds down four jobs.
