I ran across a curiosity a couple of weeks ago and haven’t satisfied it yet. Today, I googled it again and came upon a blog post that actually phrases it in reference to presidents. I know that in “the old days” many people slept sitting up because they thought it was healthier, and it was so common that beds were built quite short. But when did it start and when did it end?
Specifically, which presidents would have slept sitting up and which would have slept flat?
