As a mentalist, I am always seeking new ways to stimulate my great mind.  Witnessing my mentalism demonstrations is, of course, not only stimulating, but inspiring as well.  While I have been offered the opportunity to be a “house mentalist,” sort of a butler of the brain, this seemed impractical and interfered with my performing schedule. But there are ways for the average person to grow a better brain. For example, many exercises to stimulate the brain involve doing familiar routines  in unusual ways. This  change challenges the brain, resulting in brain cell growth and the creation of new neural pathways. Such exercises include getting dressed with your eyes closed, and switching to your non-dominate hand for activities such as shaving.  While this would result in a better brain, it may also result in disheveled appearance and one’s face looking as if it was on the losing end of a fight with a weed whacker.
My advice: don’t stimulate the brain in this manner on the night of a formal dinner. And yes, I speak from experience.
