Brilliant Or Insane

High intelligence and insanity have walked hand and hand through the ages. Society has long thought that brilliance comes with an increased risk of insanity. This common perception has yet to be totally disproved, but what has been discovered is that the highly creative, intelligent mind is more similar, than dissimilar to the disabled mind. The difference is how the individual deals with the same stimuli reaching their brain. For many, high intelligence saves the individual from insanity. So I wonder if it is not the type of an intelligence a person has that either results in a creative, high functioning individual or someone who suffers from mental illness. An interesting question that I do not know the answer to. Brilliance and insanity are closer than you think. For instance, I have a very sweet neighbor, she is a little "quirky", and has a lot of fears, her reasoning is somewhat unusual, "but" she is highly intelligent in math. She can go to the store and tell me without hesitation what the cost of a roll of paper towels are in a package of 24 is, taking her to Costco is a treat in it's self, bulk items are a snap for her to figure out the price singly ,she can calculate things like this without even seeming to think about it. I bet she could tell me how many kernels of corn in a can to make 16 ounces, It's the common sense things that boggles her mind. I don't feel she is insane, but "quirky"
