I have absolutely no idea if 2 out of a hundred is high or low. That is why I am looking for other sources for comparison
I would say its pretty low, I am sure if you did that study back in the states the numbers of smelly ****s would easily be in the double digits.
Most Thai chicks shower 3-4 times a day.
They also use that spray thing that you find in the toilets here every chance they get. With the heat here, I would hope most farangs would shower as much too.
