Look at your hand and fingers scrolling through the screen. Contemplate the regular movement of your thumb going upwards most of the time, downwards only sometimes. What a miracle to have opposable thumbs! From hand axes to your phone, the one you're staring at right now, all made possible by this little perk of human evolution. Pause for a second and look at your hand. You're looking at it right now. This image is a mirror or a window. Your phone is transparent.
