Alexander Selkirk (on whom Robinson Crusoe was modeled) was stranded on the island of Juan Fernandez off the coast of Chile for 4 and a half years.
After his rescue, ...."Selkirk eventually returned to his home in Scotland, where he became quite a celebrity. Though he did get married, he never quite recovered from his stay on the island. Spending much of his time alone, he didn't feel comfortable living indoors and built a sort of cave or bower behind his father's house that he stayed in. He also trained two cats to perform little feats, like he did on the island.
Eventually he returned to the sea and he died of fever off the coast of Africa in 1721 at the age of 45."
