I'm rather confused that you're all saying you would be stuck with your waste... Flushing a toilet has to do with water pressure, and has absolutely nothing to do with electricity in any way. So you would in fact be able to go to the bathroom as you normally would. Same goes for taking a shower, using a sink, etc.
As for when the power goes out at my house, I simply take out my iPod and my phone, put in the headphones and talk with friends. It does get a bit boring after awhile, but I manage just fine when the power goes out. And due to the amount of times my power used to go out, we did buy a generator, so if I am really desperate for gaming, television, or computer, I am able to resume using them.
