““Scientists now know the brain receives 400 billion bits of information each second. To give you some idea of just how much information that is, consider this: It would take nearly 600,000 average-size books just to print 400 billion zeros. Needless to say, that’s a heck of a lot of reality. So what do we do? We start screening. We start narrowing down. I’ll take that bit of information over there, and let’s see—this one fits nicely with my ongoing soap opera about the opposite sex. When all is said and done, we’re down to 2,000 measly bits of information. Go ahead and take a bow, because even that’s pretty impressive. We’re talking 2,000 bits of information each and every second. But here’s the problem. What we choose to take in is only one-half of one-millionth of a percent of what’s out there.””
