when I was about 4 or 5 and at my grandfathers house, i noticed that my mid-torso moved when i breathed. i thought that only adults were supposed to do that so i held a pillow against myself and took slow short breaths so the pillow wouldn't move (i was afriad someone would say something to me about it if it did). Even now i try not to move too much when i breathe.
