question for Mr. Chiang

Mr. Chiang,

In your story "Liking What You See: A Documentary," the characters have the choice of calli or not. Calli seems to only focus on the face, which fits with what I know of modern scientific knowledge of the human brain. As far as I know, humans can recognize a face, and it is separate from other recognition.

In the story, you make no mention of discrimination based on body type, which seems to be a big issue in today's society. Was this assumed to go along with the facial recognition of beauty, or is this not an issue in the society you talk about? I would be interested to know.
