Colon Cleanse?

Have you ever thought about a colon cleanse? They seem...gross and unnecessary to me. The human body is built to kinda take care of itself for the most part. It doesn't need to be "cleansed" of toxins or whatever. Your body will rid itself of toxins on its own. If anything, something like this could be dangerous. Well, if you feel like you really have to do this, be careful and make sure you talk to a doctor first.
