Modern life forces us to be creative and we need to surf the changes of marriage as we age. I no longer sleep in the same bed as my husband because we both sleep badly and wake each other up, plus our modest-sized house has a master bedroom with a tiny bathroom and a too-small closet. I don't usually offer this in conversation--because, you know, "bad marriage." But it makes no sense to sleep badly because without sleep, the rest of life isn't much fun!
