One Parasitology course changed me and the way I perceived the world forever. Parasitology: not even once
Any body of water, so lakes, swimming pools, the ocean are packed with parasites. Food, a lot of it has parasites in it, we just cook them to death first. Worms in the dirt. My own bed. The list goes on.

Did anyone’s elses teacher drop a small amount of sea water on their head, then he put a drop underneath a microscope, causing everyone to collectively freak out? That was mostly plankton, though.

The entire world is covered in a fine layer of poo particles. Really, anything that isn’t covered in poo is the outlier and ought to be highly suspicious.
