" Every instant of every day we are bombarded by information. In fact, all complex organisms, especially those with brains, suffer from information overload. Our eyes and ears receive lights and sounds (respectively) across the spectrums of visible and audible wavelengths; our skin and the rest of our innervated parts send their own messages of sore muscles or cold feet. All told, every second, our senses transmit an estimated 11 million bits of information to our poor brains, as if a giant fiber-optic cable were plugged directly into them, firing information at full bore. In light of this, it is rather incredible that we are even capable of boredom. "
