The real reason China's destined to be a superpower:

They get their kids toilet trained by 24 months.

Yesterday we went to the river with our lovely new friend Cathy, a Chinese woman who's studying English, and her 20-month-old son (that's right, SON, notoriously harder to train than a daughter), and he was completely day trained. Blanca was wearing a pull-up for the excursion. The kids sat down to play with another little girl, just two, and her mother expressed surprise that Blanca was wearing a diaper. We hung our heads in shame.
