The reasons why people willingly undergo the travails of difficult journeys.

People like Nick Middleton and Edward Michael "Bear" Grylls undergo the travails of difficult journeys for not just one single reasons. They like to explore and experience the adventure. Risk is the biggest of all addictions in the world and the challenges they take on gives them the perfect rush. Nick is a geographer who likes to expose himself to nature. He likes to survive the extreme and hostile conditions, like starving oxygen. The programme Going to Extremes is about the extreme lifestyles he survives on. The adrenaline and the excitement of these unusual experiences is unparalleled and unmatched. It is an addiction that these explorers dwell on. It is their food for living.
