Lead in the environment is one of the leading theories behind the reduction in crime across the board we have seen since the early 90's. Essentially lead was damaging brains across all groups of people pushing otherwise stable people into crime.
I loved this episode but thought they didn't discuss one assumption in dating the earth and why it is valid. Using meteorites to date the earch assumes that the meteorite is the same age as the earth. Other than covering that a little more the episode was perfect.
