You might have heard that the average body temperature of human beings is not the same for all ethnic groups. The Japanese claim that their body temperature is lower than that of Westerners. I did the test on my wife and I, with the same thermometer at the same time, and indeed her temperature is 1'C lower than mine (35.6'C against 36.6'C). Of course one example is not very significative, so I would like to know what is your average body temperature and your ethnicity, so as to see if it is really linked or not.
