You are all getting far too technical...A simple test will sort this out easily.
Take 2 litres of water, 2 liters of beer and 2 liters wine
Obviously the beer and wine parts of this will need to be carried on separate occasions so as not to interfere with the test results. All liquids must be consumed within a designated time frame, for this test time is 1 hr
My Hypothesis on this test are as follows
2 liters of water still thinking about the feces you may have just consumed, along with the trivial day to
day problems that plague us (what's for dinner, damn I feel sick after all that water etc etc)
2 liters of beer still thinking...more about the fact that more beer is needed as I now have the taste for
more...that food would be nice but not really necessary..and wow that chick is looking
mighty fine etc etc
2 liters of wine still thinking....yeah right you are hahaha
