1. Most of the postures we adopt and the movements we make have been made by us thousands of times before. A. In many cases, they are so familiar, so much taken for granted that we do not even know how we do them. B. For example, when people interlock their fingers, one thumb rests on top of the other. C. Most of them are performed unconsciously, spontaneously and without self-analysis. D. For each person, there is a dominant thumb in this action and whenever left and right hand interlock, the same thumb rests uppermost.
2. Yet, hardly anyone can guess which is their dominant thumb.
