Why are there morning people and night people? How come time flies when you’re having fun and three minutes can sometimes seem an eternity? Would time exist if we didn’t measure it – and why is there never enough of it?Our modern lives are ruled by minutes and hours. We race from one thing to the next, all of us believing on some level that a mysterious cosmic force called ‘time’ is ticking on. And it’s always in short supply. But is the time we live really like that? Could there in fact be another, alternative version, entwined with the official one? Here Stefan Klein explores the hidden dimensions of time, looking at everything from when the present becomes the past to the tribe that see the future backwards, from when sex is best to why the years seem to speed by as we age. And he reveals how we can learn to live in harmony with the secret clock within us, altering our perceptions to transform our lives. To be enjoyed in the morning or the evening (depending on your body clock), this book will make you think the next time you check your watch – and maybe even slow down a little.
