I agree that 'soldier' is not good for all the reasons given.
My problem is that I find lying on my side or front for any length of time quite uncomfortable. Even if I do manage to get to sleep that way I always seem to wake up on my back.
I think I do most of those throughout the night, plus the leg out of the duvet. Start out as a yearner then on to the freefall. Usually wake up corner to corner. The OH sleeps like a soldier.
Nah - load of rubbish. I (and I'm sure everyone else) sleep in whatever position is comfortable. There's a theory now that body language is not as reliable as once thought. They say you need to have about 3 similar 'tells' at the same time for it to be accurate - for instance, having your arms folded doesn't necessarily mean you are defensive. You might just be cold or have no pockets and don't know what to do with your arms. If it is combined with 2 other defensive attributes however, then it is more likely that is how you feel.
Lol, well according to that im a foetus and Mr Smow is a freefaller, though he sleeps with his face down in the pillow, and not to the side. God knows how he hasnt suffocated!
