We use our five prime senses every minute of the day. The sense of touch varies over the entire surface of the human body. The sensory "homunculus" illustrates how the areas with most sensitivity for touch govern our bodies. Our fingers feel the world in sensory high definition by containing the highest density of touch receptors in the body. This means we can distinguish two points of contact – imagine moving two pins closer and closer together on your finger until you only perceive one touch – only 2 mm apart. This is 22.5 times more sensitive than the least sensitive part of our bodies: the calf.
