We all need something to believe in, whether it''s God, money -- or naked table tennis. But has anyone actually cracked the secret of how to live a happy life?

Meet acclaimed comic bloggers Tom Fordyce and Ben Dirs, two men in search of meaning in a meaningless world of work, Facebook and microwave meals for one. It''s time to become ''karma chameleons'' and try some very different ways of living. What follows is a weird and wonderful year sampling life as silent monks in the far north of Scotland, and as witches in an East End coven; weeks spent living solely on the Internet as avatars, and entirely in the real world, as naked as the day they were born. And along the way, Tom and Ben encounter a whole host of odd, hilarious, charming people, all fellow travellers on a quest to find the secret of happiness . . .
