The Stranger in the Woods
At 20, Chris Knight set off into the woods to avoid society. He didn't come out apart from to commit petty theft for supplies for 27 years, when he was finally caught after about 1,000 burglaries. Catherine and I are a bit divided on this story -- I think Chris clearly had something wrong in terms of mental health, whereas Catherine thinks he crossed a line when he committed theft to survive. Either way, I don't think you could claim that Chris was living in luxury in isolation, especially when research has shown that extended isolation is generally very bad for mental health. I came across this book because Digital Minimalism recommended it as a good exploration of solitude, but most of the book really isn't about that. Mostly the book is a description of Knight and his life for those 27 years. That said, it's still an interesting read. I'd avoid the book if talk of suicide is a trigger for you, although Knight does not appear to have carried through on his threat.
