Could you live without electricity?

That was the one of our conversation issues in my class, yesterday.
It sounded a little bit weird. I hadn't thought about it before.
Anyway, in the future, after some an unforeseen accidents, if we have to live without electricity, how long do you think you can could endure that condition?
I thought, in my case, at most a few days, maybe?
If it is winter, things are going to be more painful.
But, maybe in summer, I might endure that situation a little bit more longer than in winter, even though, food will rot if the refrigerator doesn't work. and I will not wouldn't be able to use the electric rice cooker, computer, cell phone and or the other electric devices.
Oh, and I might not be able to go to school or somewhere else, because the subway wouldn't work.
The one thing to that would be interesting would be is the possibility that we might be able to see stars in the sky even in Seoul.

Your english is very good, I just corrected a few nit-picky things. :) Also keep in mind about run-on sentences, try to minimize having so many ",'s" in a sentence. For example, "It was very hot today, so I have a fan to try and cool things down, but it's not working, so I will open some windows when it gets cooler" doesn't sound as good as "It was very hot today. I have a fan to try and cool things down, but it's not working. I will open some windows when it gets cooler".
