Does a colon NEED cleansed?

On the message board I post on the topic of colon cleansing came up. I have to wonder if a colon is something that really needs to be cleansed. I am a firm believer in our bodies taking care of themselves and really don't like to mess with that.

I know that there are colon cleansers out there that claim that your colon has pockets in it that waste gets stuck in and it festers there for years and causes all kinds of sicknesses and problems. I just don't believe it. I think it is a bunch of hooey. Well...for ME anyway. I mean to each his own of course...but you won't catch me cleaning much...colon included.
