littlestream SG hee hee..... no, what I am trying to say is, after reading BabyLover's post, I tried a little test, i.e. to THINK. So, as I think, my eyes voluntarily rolls to the right and look up. If you read BabyLover's post, it indicated that we typically roll left. So, I tried to roll left and look up but it gave me a "kuai kuai" (strange) feeling. Very not "tzi run" (natural).
