Heres some pretty low tech transhumanistic thinking for you. I found the thought cross my mind last night of whether we could direct the bodies plumbing so that the bladder is removed, the bowels enlarged, and all fluid waste is directed straight into the Bowel. This would grant us several advantages. A larger waste holder, so we need to 'go' less often, and when we do, it takes care of both. Plus it makes the rear end the waste disposal system, and the front end the entertainment area completely. No halvies. It just seems a little more logical. The problems with is which I can already see, are that there may be moisture seepage from the anus. I don't really know how watertight that is. Secondly, farting is obviously in existence for a reason. Gas builds up and makes u feel like you need to push something out. Since the liquid would rest in the bottom of the bowels, and the gas would fill up the bowels so that you feel like u need to go, i guess pushing the gas out would cause some leakage. Maybe this is the biggest problem and needs a real solution before such a change could be made to the human body. Would anyone else think that such a change could be handy/practical?
