Is the correct position for the kipa always above the head or does it change as you change positions? For example if you hang upside down does the kipa still need to be on "top" of your head or should you move it to the side (back of the head, or chin)? How about when you lay down on your back or belly?
Question Motivation: When you lie down in bed and need to recite a blessing, do you need to reposition the kippah or it's fine in the regular position - the place it would be have been had you been standing and it would be above your head.
