Does anyone here know anything about bowel movements?

Thanks. How often should this take place? I haven't had one in a few days :-\

Please read that site. If you're worried, contact your doctor.

I'm not concerned; it's just a homework question. For science class, I'm supposed to be keeping a log of my activities, along with any unusual observations.

Yes, I can help you with questions about bowel movements. What specific information are you looking for?
