According to neurologists, our brains have a storage capacity of approximately 2.5 petabytes.6 That’s the equivalent of recording three hundred million hours of high-definition television! Simply put, we have the capacity to learn something new every second of every minute of every hour of every day for thousands of lifetimes! We won’t run out of hard drive space anytime soon. And the three-pound supercomputer inside our craniums runs on less power than a twenty-watt lightbulb.7 Amazing, isn’t it?
