Does anyone else ever just sit and stare at their fist and clench…unclench…clench…unclench?

I'm just thinking about everything that is involved in such a simple action: the oxygen required and the immense delivery system that gets it there, the bone structure, the muscles that move the bones, the neurons that tell the muscles how to move, and the complex workings of the brain that tell send the message down the neurons. To think that such a complex system evolved by natural selection over the course of millions of year…absolutely incredible.
