Now I'm going to say a word: po-po-posture. Mmm. Now, there's a nice Ti-i-ime magazine, working-for-you, in quotation marks, it's a legger now kind of word, isn't it?
Posture. Sort of makes you sit up and listen. M-m-m. Sit up properly and listen.
People sleep in beds with posture springing. Well, most people, except, how shall I put it right off the top of my head... the Japanese. The Japanese don't have beds, they sleep on a fu-ton. Futons are very popular and very expensive, and they consist of nothing more than a stuffed sack. Weird. Well. Very good for your posture, and they help you relax and dream.
Mostly about sleeping in a proper bed
