Well, AlexanderWeeks, thank you for your comments, but I hereby argue that there's a big difference between using 100% of your brain and using 100% of its potential. For example, Einstein did amazing stuff with his brain not because he used more of it or because it was fantastically better than other people's (it was maybe better, but not fantastically better), but because he made much better use of its potential. He habitually thought about difficult problems, and in a deeper and more tenacious way than most scientists do. ANYONE could think deeply and tenaciously about very challenging questions if they so chose, but most simply don't. I encourage you to not embrace the proofs and disproofs of so-called experts. Be skeptical of everything and everyone. When the brain is open to all possibilities, you open yourself to surprising levels of discovery. In my opinion. ( :
