Where do shit go?

Have you ever wonder where do shit go? I know I know, shit go into toilet bowl. But what's the process after that. Yeah I know, it goes to the sewage system. But how does the sewage system function? Do you know? I don't. In JB we can see 粪池 here and there, but why doesn't it smell? I always wonder.

So I search from www.howstuffworks.com to look for an answer. Quite interesting, if you want to know : Sewer

P.S. Think I'm disgusting? for I talked about shit in two posts.. Well, Aries are disgusting bunch of people who would ask things like "How smelly is the fart?". hehe... I read from a book when I was little, that when you're in the bathtub and you fart, if you're quick enough you can "catch" the fart by turning a glass facing the water and "catch" the gas when it rises and pops from the water surface. haha... that's interesting.

And while I was diving, I sometimes fart. And the air that I release, won't just come out through my wetsuit (at my butt there). Instead, it'll "rise" and come out through the opening at my neck. I had often worried that other divers will notice the air coming out from my neck and they'll know I just farted... hahahaha...
