In the late 1980s I spent a year in the US as an exchange student. The exchange organisation allocated me a local support person named Emily. Emily was white and loud and the fattest person I had ever seen outside a caravan park. She looked different from the rare very fat people I'd seen in Australia. She smelt good and her climate-controlled house meant she did not sweat. She was very well dressed. Her husband was some kind of professional; I didn't know they even made suits that big.
