When I was writing 'The White Tiger' I lived in a building pretty much exactly like the one I described in this novel, and the people in the book are the people I lived with back then. So I didn't have to do much research to find them.
People wince when something is in bad taste. They laugh when it's funny. If it's too dirty or wrong, they won't laugh. But if it's a big, dirty, smart, funny laugh, they love it.
I don't happen to think magazines should be full of thin people. What I do say is that we can all work a little harder with what we have. It is possible to achieve a better body shape and heart rate with nutrition and exercise.
