Evolution really looked at this big long list of gastrointestinal diseases we as humans can suffer from, and thought that traumatizing amounts of random nausea, constipation, diarrhea, and tummy hurt would be enough for us to figure out when we're supposed to be eating more nuts and less berries, or whatever the hell. I hate it.
