I don't know exactly I'm not a naval guy--

我不是个海军不清楚是不是完全这样
but half an hour later this thing starts to move and thing this is

但是半小时后战舰终于开始移动了
long before it started to move you're already turning back,

但是问题是在它转动之前你已经往回转了
because it's going to move way too far

因为如果你像平时开车那样开战舰
if you try to steer it like you'd normally steer a car.

在要转弯时才打方向盘那会为时已晚
American politics and policy making is like a battleship

在肥胖率和很多其他公共健康问题上
around obesity and many other issues in public health.

美国的政治和政策制定就像一搜战舰
You turn, and you turn, and you turn and nothing happens

你尝试一点一点的转变但是毫无作用
and then once you realize this thing actually turned,

一旦你意识到事情有了转机的时候
you've gone way too far.

却常常已经过犹不及了
Let me not--I don't know if that will happen

我不知道在降低肥胖率和增加食品营养
on obesity and associated nutritional issues.

这些问题上是不是也会这样
