At first I didn't quite know how to take this. However as always with short pieces you have to dig below the surface to get the true meaning.
Society is like bowel in the sense that movement can be healthy - I think what I got from this is that society is pretty much like poop it's dirty and is quite content to sit around doing nothing most if the time which can be unhealthy but when movement happens it opens up the bowels- life to accept new things- ideas which can be a lot healthier for people.
