Northern Chinese are tall - perhaps, due to wheat?

In China, as in many countries, the north-south divide runs deep. People from the north are seen as hale and hearty, while southerners are often portrayed as cunning, cultured traders. Northerners are taller than southerners. The north eats noodles, while the south eats rice—and according to new research, when it comes to personality, that difference has meant everything.

A study published Friday by a group of psychologists in the journal Science finds that China’s noodle-slurping northerners are more individualistic, show more “analytic thought” and divorce more frequently. By contrast, the authors write, rice-eating southerners show more hallmarks traditionally associated with East Asian culture, including more “holistic thought” and lower divorce rates.
