How much do you need to spend your retirement life?

I'll show you this article of our newspaper, you can read the number 27.9.
According to it, in Japan most of people think that we need 279000 yen a month to spend our retirement life,
How about your country?

Well, when I saw this article yesterday, I made a bitter laugh.
This month we got the last salary. Our real retirement life will begin in three days.
We were talking a lot for this year about whether Yuki continues  to work  in his present company or not. And we checked our saving and decided not to extend his contract.
