Thirty five years ago, Robert Ader, PhD serendipitously discovered a key part of our physiology that was not thought to exist. The story begins with rats drinking water sweetened with saccharine. Half the rats were simultaneously given low doses of Cytoxan to cause stomach pain. (Cytoxan is a chemotherapy drug for cancer.) It was no surprise that soon the rats associated the sweetened water with the pain and refused to drink it.
