Begins with a six and ends with a zero

Today is Sally's birthday. It's a big one. On such occasions, especially if one is talking about the fairer sex, one always says the person doesn't look it. But really, she doesn't. Perhaps fortysomething? We celebrated, if one can celebrate such occasions, at a peking duck restaurant.  Coincidentally, our first peking duck experience in Beijing happened to be on Andrew's 60th.
