Genius
– An individual with an IQ above 139, as opposed to someone who is simply called one because he has made a lot of money.
Contrary to popular belief, geniuses don’t usually wear glasses. They do, however, frequently tend to be excellent physical specimens, less prone to mental disorders, physical weaknesses and body deformities than the general population.
Among the general population, the odds are 1 in 250 that any child tested will be revealed to be a genius. Recent intelligence measures have tended to categorize the most intelligent as a “first order genius” which occurs in 1 in every 1,000 births.
