500,000 years of milk and cold-temperate weather.  the best asians are the ones who drink the most milk and live in the cold. the best middle easterners drink the most milk and live up in the mountains. even the toughest niggers (besides the ones who are like half white in ethiopia or whatever) are the ones who live where it snows. stay away from warm lowlands and river deltas, especially equatorial river deltas, they're a disaster for your people's mental and physical health once you've been there more than a thousand years. intense temperate climates literally increase pattern recognition and long term planning ability. pattern recognition is what makes people people. the more you recognize patterns and can plan accordingly the more human you are. cold weather makes you better, but cold-temperate (four seasons, with killer winters) makes you best.
