John! There you go again giving people outlandish suggestions.
Use your whole brain. Geesh! What are you trying to start here? A "thinking revolution? Careful what ideas you plant. You wouldn't want to be responsible for causing mass synapsial overload due to firing up old rusty cicuitry, now would you?
Besides the Corpus Callosum would never take the sudden demand of such "balanced" brainflow. Most people are quite content using what little of their brain they find they need to, to function in our society. In fact from what I've seen, many don't use their brain at all. Brains do however, make good ornaments and can be a nice addition to any decor.
