the prospect of having to eat more and more

但要让我一直不停地
and more and more and more chocolate,

不停地吃巧克力
eventually the idea becomes a sickening one.

那最后就我就想吐了
Think of any activity.

随便举任何一件事
Some of you may enjoy doing crossword puzzles,

你们有些人喜欢玩填字游戏
and perhaps doing crossword puzzles a couple hours a day is enjoyable.

可能每天花上几小时玩玩字谜很有意思
But imagine doing crossword puzzles every day

但设想让你日复一日地猜字谜
for 10 years, 1,000 years,

十年一千年
a million years, a billion years, a trillion years.

一万年一亿年一兆年
Eventually, presumably, so it seems to me,

最后在我看来
you'd end up saying, "I'm really tired of crossword puzzles."

你大概会说 "我实在不愿猜字谜了"
Sure, there'd be some new particular puzzle

当然还会有一些你从没见过的
