The palms of your hands and the sole of your feet especially the fingertips transform from smooth to wrinkled after getting soaked in water just for few minutes. Wrinkling is not just absorption of water into the protein rich outer layer of the skin, but it is an active, adaptive process controlled by sympathetic nervous system. Pruning of the skin occurs to help us grip objects better in wet conditions. They allow water to slide from the fingertips and the surface of objects we are trying to grasp ( bar of soap).

Does the eye twitch annoy you?
