There are over 150 trillion cells within the body. If set end-to-end, these cells would encircle the earth more than 200 times. Today medical students learn of more than 1 billion miles (1.6 billion km) of DNA in one human body. The brain continually receives signals from 130 million light receptors in the eyes, 24,000 hearing receptors in the ears, 10,000 taste buds, and hundreds of thousands of receptors in the skin, with specialized commissions to recognize touch, vibration, cold, heat, and pain.
