“At the age of 20, Christopher Knight parked his car on a remote trail in Maine and walked away with only the most basic supplies. He had no plan. His chief motivation was to avoid contact with people.” Michael Finkel describes how one man survived alone in the woods for 27 years. “Knight parked the car and tossed the keys on the centre console. He had a tent and a backpack but no compass, no map. Without knowing where he was going, with no particular place in mind, he stepped into the trees and walked away.” This act’s modern day equivalent would be to turn off your WiFi for a few hours.
