I watched the TV series "Cosmos". Was hooked and fascinated.

Carl Sagan's IQ was 170. The IQ of the average American is 95. The designation of "mentally challenged" begins at 70. So, the average American is 25 pts. from mentally challenged, but 65 pts from genius, and 75 pts from Carl Sagan. The average person meets roughly 100,000 people in their lifetime. Of all of those people, only 1 or 2 will have an IQ above 140.
