Studies have shown that couples who sleep in separate beds have better sleep than those who sleep together. This, to those of us who are children of the hedonistic 70s and 80s, seems to be completely, so to speak, "wack". The numbers, however, prove it: a noisy, lumpy neighbor who keeps rolling around and steals the covers is actually a detriment to quality sleep. Well, when you put it that way, it makes sense.
