"<a href=""https://www.youtube.com/watch?v=hppbxV9C63g&amp;t=20m55s"">20:55</a> "...the higher your IQ at 11", the higher probability you'll still be alive at 79...": I call nonsense. (1) Notice that up to age 30 you can't see any real difference...yet the curve is already showing 5 years more life for the smart over the stupid. (2) Notice the order never changes...stupid at the bottom, smart at the top. That's counter intuitive. Ever hear "the good die young"? (3) Notice at 50 95% of the people are still alive. But of those dead, the dispersion doesn't change. And if you take the stupidest at age 45, he's as likely to be alive as the smartest 5 years later at age 50.  (3) And at 70, the stupidest is as likely to be alive as the smartest at age 79. So being smart gives you 5 to 10 years more life. Now do your factor analysis...surely you're bright enough to do that. <br><br>What killed the stupid people. And what killed the smart people. That's the curve coming next...right? <br><br>We know the stupidest among us are cops...it one of the screens for hiring them. And cops have dangerous jobs. But the second stupidest among us are psychiatrists. Are they being killed by their patients...or are they just committing suicide.
