This is a very interesting article about how Homo Sapiens, mainly native people, keep their bodies pain free and mobile simply by the way they sleep. 

There is some great information in the article that I have been testing recently, with great results. If you are brave enough and want to heal your back and joint pain while you sleep, read the article and try out the sleeping postures.

It takes a little getting used to but I have noticed results since the first restful evening.

Yours in health
