It appears that Heinlein at least attempted to live in a manner consistent with these ideals, even in the 1930s, and had an open relationship in his marriage to his second wife, Leslyn. He was also a nudist; nudism and body taboos are frequently discussed in his work. At the height of the Cold War, he built a bomb shelter under his house, like the one featured in Farnham's Freehold.
