Fat + brain tissue = constant I think I have discovered a new law of medicine. Has anyone else noticed how fats tend to be less intelligent, and the fatter they get the more delusional and irrational they are? there are few if any Nobel prize winners, National Academy of Science members, etc. who are obese. I think we can safely state that the amount of brain matter plus fat in a given individual is constant.  Actually, scratch that. The amount of fat plus brain matter is less than or equal to a constant (often there is not enough initial brain matter to account for all the fat). We should call this the FPH constant,
