What does it mean when you sleep on your back , one hand behind your head and the other hand in your PJ's.?? ........... that study is so stupid , because i sleep all different styles face down, faced up, left side , right side, hell even i do a hole 180 turn in the bed. STUPID Research ..... what a way to spend Tax payers money huh ?? How about sleeping next to the toliet after a long night out. .... that be the only sleep that i could identify as being " f*kED UP ! " ..... " thats what I think" [smiley=headscratch.gif]
