Diabetes
This is the story about what powers the engine of life. In order to survive from second-to-second, minute-to-minute, and carry out the daily activities of life, you have to have energy, and you have to be able to extract that energy from the world around you. For most of life (with the exception of the creatures that live in the deep oceans next to the thermal vents) that energy ultimately comes from the sun, and that is where the story begins.
