The human brain is such a wonderful gift to man. It is extremely complicated, incredibly powerful, and, truly, there may not be a limit to what the brain is capable of accomplishing. The brain learns, trains and changes itself. It holds many unbelievable secrets within it, and it will not readily divulge them, unless you coax it, and demand of it. But whenever you do so, it surely will reveal or deliver to the extent of your demand on it.
