Is it normal or common to rock back and forth during the daytime which is not related to a rhythmic movement disorder?

Is it "normal"? Well what's normal in today's world? However, it could be compulsive disorder or just your personal form of mantra meditation. That's what's so good about being an American, first and given the choice of making a choice by God Himself...Nice arrangement huh? My advice...quit worryin' about it and get a hobby and don't worry about things like "Am I abbie-normal if I rock back and forth occassionally when nobody's around?" Live my the late great Bruce Lee would say at this time... "Be water my water..." Good Luck, PJ
