More common world wide I would say, but probably not more common in the States.

I think religions like Hinduism could probably teach me a lot about this, seeing as they have a strong connection to the physical body (which I admit to being fascinated with).

In addition. I do see life on earth as being a place to connect your soul and body.
For example, I am very committed to yoga, and part of practicing asana is to unite the soul with the body in order to rid the self of duhkka (essentially, bad energy).

I do believe in the soul/body connection! Just not after our bodies are buried in the ground :)
