Evidently I snore too much, so my wife sneaks into the guest room often, after I'm asleep. We both would much prefer staying all night together, but her sleep is important. I can sleep through anything, and in fact I've fallen asleep in a crowded stadium, and I even slept through a car bombing in Marina Del Rey in the 1980s, and woke up wondering why the hotel window was busted, and there was glass in my bed. But my wife wakes up if the house makes a noise as the attic cools off at night. I've tried all kinds of medical advice to stop, and I don't have sleep apnea or any abnormalities that can be corrected. So it's just plain old snoring.
