What is Disease? (The Unseen Enemy) (1x24)

:

This short profiles an average individual man. He may know how to protect himself from hunger and a thunderstorm, but how can he be protected from the unseen enemy, disease?! The short proceeds to discuss the technology of microscopes and the existence of microbes. Worst-case scenarios are again played out and if the reused warnings about mosquitos and not using latrines don't get you, you may just develop a fear of water.
