sense of timing

the naked traveler did a piece on people's sense of timing, which reminded me of a graduate class i had a few years ago in america. there were 6 students, each of different nationality. the american would arrive early (even before the professor or purposefully waiting for the professor so that he could walk into class with him - personally I think it's all kiss ass), the Dane right on the dot, the Russian one minute late, the Indian and the Indonesian took turns being second-to-last, and the South Aafrican last, his gait (in my mind) to the beat of reggae. It's genetic, I think.
