Will Blunderfield grew up, he says, an unhappy, unhealthy kid. Now he feels great — as a “wild naked man” who drinks his own urine.

Across the world, wellness is a multi-billion pound industry, even though some of its practices are unproven, extreme or even harmful. So why are so many people unimpressed with what 21st century medicine can offer them, and turning to internet gurus instead?

The New Gurus is a series about looking for enlightenment in the digital world.
