I wonder, if elevated levels of peptide-Y are enough to stop the flies from seeking other rewards, isn't peptide-Y a narcotic in itself?
These kinds of studies are very important to biomedical science. Using a fruit fly model is much cheaper and easier than using larger animal models, so 'crazy ideas' are more likely to be tested.
Like fruitflies, I think it's understandable that those people who are rejected want to drink more - it numbs the pain. Sometimes, it's about the only thing that does.
