Times have changed since Fiddler on the Roof’s Tevye sang If I Were a Rich Man and fantasized about the day when his wife would have the physical attributes associated with wealth: “Yubby dibby dibby dibby dibby dibby dibby dum. If I were a biddy biddy rich, idle-diddle-daidle-daidle man. I’d see my wife, my Golde, looking like a rich man’s wife with a proper double-chin.” Today, 70% of Americans wish they could lose their double chins. And the FDA just approved an injection that could make that wish come true. Oy.
