I was a little skeptical myself. "data from the step-counting app Azumio Argus" - they counted steps. I can see how they might walk less as everyone gets around by motor scooter there which often involves less walking that using a car as you can normally park the thing at your destination rather than schlepping around looking for a car park. But I wouldn't really call them sedentary - they are quite a hard working bunch on average.
