When I had just started high school, there was a three day / two night camping trip out into the hills nearby. In these hills, the only place you had to crap was some old dingy outhouse which everyone used and I don't believe had any real flushing system at all. I dind't like the look of it, so I didn't go.

Yeah, that's right. I just didn't. That means for about 48 hours, I held it in. Yikes. I can't believe that now, I can't last as long as I used to.

On a sidenote, my birthday was the day inbetween the two nights. I turned 13! Two days afterwards I got my first girlfriend. Good times.

EDIT: The more I read about this whole "only 12 hours" stuff everyone is saying, the more I wonder if I actually did go to the toilet and I just don't remember. o_o I wonder what the 'world record' is...

EDIT: Apparently you need a kidney transplant if you don't urinate for 14 days. Dude! 14 days!? Who the hell goes without peeing for fourteen days!? I thought that'd be you dead! D=!
