Put it this way: From a public health perspective, we don't know who'll get into a car accident, but we tell everyone to wear their seat belts.

可以这样说：从公共健康的角度来说，即使我们不能预测谁会遇到车祸，但是我们会告诉每一个人必须佩戴安全带。

If we don't wear our seat belts it doesn't matter, because we have air bags.

如果我们不系安全带，那也不打紧，因为我们有气囊。

Eat your vegetables. Don't smoke. Wear your seat belts. We all know some basic ways to help extend our lives (even if we don't follow them). But how do we extend our careers?

吃蔬菜，不要抽烟，系上你的安全带，我们都懂得这些延年益寿的基本方法。但是怎样延长我们的职业生涯呢？
