There are no fat people here. None. The absence of pudge makes itself known as a lacuna, a statistical fluke. We place bets on how long it will be until we see our next genuinely obese person, but after half a day without one, we give up. Once, we think we have spotted one, but he is sporting a fancy camera and shorts, and looks distinctly like every stereotype of an American tourist.
As an even odder counterpoint, Sarah observes that anorexic-looking people are almost equally conspicuous by their absence. The Austrians just seem to have healthy habits -- although, between beer, schnitzel, and the omnipresent bakeries, one would expect every sort of poor dietary practice imaginable.
This turns out to be a specifically Austrian phenomenon: in Budapest, we see plenty of heavyset people (although none who are actively obese) and Sarah is beside herself with joy at the total lack of whippet-thin model-esque bags of bones. Prague is the exact opposite: hyper-thin belts worn loose over pants far too tight to require a belt is the in style, and the matching body type is also in.
