Do you sleep N/S or E/W.
After some research I am convinced from the physical evidence, that N/S is the position for me. I think when I wake up all the electrons in my body have been lined up nicely by magnetic north, and I feel as strong as an ox after every sleep I have.
Feng Shui recommends E/W with your position in the bedroom, such that you can see your door, together with having your back to the wall, well this is simply a power position that safeguards you against any nasty surprises.
The Islam masses sleep facing East, but this is only a tip of the hat to religion and their beliefs in resurrection, similar to how graves are lined up to achieve that facing east postion.
