Hello again from Zimmerbaby! You know, it seems as though my skin is quite wrinkly.  It folds all over the place.  Hopefully it won’t be like this forever.  As I go about my day I flip all over the place, but I’m starting to get a sense that there is a force, if you will, that helps me tell the difference between up and down.  I am starting to prefer to rotate one way or the other more than just free floating in any direction that feels best.  For some reason upside seems to feel nice.  Yes, I think I am starting to prefer that position.  We’ll see though.
