Charles Foster is one of those rare people who seem to cram several lives into their own allotted span while the rest of us just about manage one… Adopting a sort of method-acting approach to research, the book opens with him and his son half-starved, certainly wet, tired and famished, as they try to experience what it was to be a hunter-gatherer. Full of the unexpected, spilling with ideas, anecdote, and intelligence.
