An idea can be tested, whereas if you have no idea, nothing can be tested and you don't understand anything. The molecule that you make when you are getting sunburned or when you eat a lot of food is part of the same molecule that contains an endorphin or an opiate. No one has ever had a hypothesis about why the two are together.
