Can You Really Sleep Anywhere?

If I had a dollar for every time I heard someone say they can sleep anywhere, I would be insanely wealthy. Yes, you probably could sleep on any mattress if you absolutely had too. When the body is tired, it will do whatever necessary to get some rest, even if that means sleeping on a concrete floor. However, the body will not get the deep recuperative sleep it needs if it is constantly adjusting, developing numbness in the arm, or simply just restless from pressure and alignment issues.
