"It is better to have one seven-foot jumper on your team than any number of six-foot jumpers."Since I mentioned IQ testing, I have two personal anecdotes on that topic. When I was in fifth grade, I was given an IQ test. One question that I remember from that test was to choose the type of person most like a physician. Two of the choices were a lawyer and a plumber. The "right" answer was lawyer, since physicians and lawyers are both professionals. The answer I chose was plumber. When you consider all the piping in the human body, such as arteries, veins and intestines, plumbing makes the most sense. That test also asked for my birth date. I knew the day and month, but I wasn't quite sure about the year. I remembered its being an odd number, so that narrowed it down to 1947 or 1949. I chose 1949, which made me two years younger than I really was. Since IQ is the ratio of "mental age" to physical age, if I was a normal ten year old, that change would have given me an IQ of 125. They do check these things, don't they?
