Dupe

The higher you go, the finer you would have to tune a much wider variety of questions. Also, you would have to test people with the same basic experiences within the same age group.

This stuff quickly becomes invalid as the population ages. I would expect to test the top of this test (or damn close). I would expect you to do the same, along with your son. But I'd probably be hitting my max, where your gene pool would just be taking off.
