good question @ Timewise 60+South, if my head is on my pillow! The rest you can figure out from this...
A much harder question is what direction do your toes point when you are in bed?
Wow, seems that if you sleep on your back your toes would be pointing up, which of course, is not South. Please correct me if I am wrong....South. Sleep on my back exclusively but sometimes briefly on my side before drifting off.
