"In one study from 2008, rats forced to run wound up with significantly more new brain cells after eight weeks than those who ran when they chose, even though the latter animals ran faster. "

This earlier study's conclusion that the forced aspect was more important than pushing the exerciser outside of their comfort zone. It seems like they should experiment with 45rpm forced exercise to see if that has the same effect. Though, it may have been just the article making that logical jump.

I would say that the society's most successful are often the ones benefiting the most from the law and order provided by government. If the highway, mail, law enforcement, and judicial systems, for example, didn't work as well, it would be much harder to create a successful business.

My anecdotal evidence says that the teacher makes much more of a difference than even the students. In my high school, every single kid that took AP Calculus got a 4 or 5 because the teacher was great, and barely anyone passed the chemistry exam. In a competing high school not far away it was exactly reversed: there was an effective chemistry teacher and every kid got a 4 or 5, but somehow they struggled in calculus.
