You have 150 billion brain cells that together are twinkling with the circuitry of a thousand cities. Your ears can hear 1,600 different frequencies, ranging from 20 to 20,000 cycles per second. Your eyes can detect a single photon of light. And the 800,000 fibers in each of your optic nerves transmit more information from 132 million rods and cones to your brain than the world’s largest optical computer system. The more than 300 million tiny air sacs in your lungs provide oxygen to the 100 trillion cells throughout your body. Your 206 bones and 656 muscles form a more functionally diverse system of capabilities than any known creature. And these and other tremendous abilities to function and learn can be applied in many different ways. You can’t count all your capabilities - there are too many.
