oh no

Microbiology is one of the few professions that motivates you to wash your hands before you go to the bathroom.

I'm sure most people wash their hands on their way out.
- unfortunately not always
  
  Fox host says he 'hasn't washed hands in 10 years'
  
  Many Americans don't always wash their hands after going to the bathroom

Ignorance is bliss

One Parasitology course changed me and the way I perceived the world forever. Parasitology: not even once

What did it ruin for you?
- 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.
- Glasses of water

Is this like learning that the splash from your toilet bowl sprinkles a bit of water on your toothbrush? Essentially a pure infohazard that makes tour life worse with no benefit?

Just like the bacteria in drinking water, you can't see it, taste it or perceive it in any way and it poses no relevant health risks. Your bathroom is flooded with poop particles even if you close the lid before flushing. It's just a fun fact and nothing to worry about, really.
- 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.
The benefit is learning to close the lid before you flush. If you flush unlidded anyway... that's gross.
You keep your toothbrush in the bathroom?

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.

Your teacher is Hella rad

Learning about all the bugs that live in your hair and eyebrows made me lose a few nights of sleep.

My hydro homies will still rise up.

What do you think about my unfiltered spring water

As a chemist, I'd say it's great for watering decorative plants and flushing the toilet.
Bruh. Our well had a fish living (and dying) in it for a while. The human body can handle some weird stuff.
- I didn't want to say it first! But a huge salamander was living in the water holding tank last I checked! It seems to have gotten swept in during the hurricane in September, and I'm not sure how to get it out as the water in the tank is nearly 10 ft deep.
  
  I've never seen that before though--the system is pretty tight. The water comes out from under a huge oak tree into a sheltered area, and stays sheltered until it comes out of the tap. Nobody has ever gotten sick off it to my knowledge... though the salamander is a new development!
  
  I'd love to get the water tested, but I haven't looked into it other than some local offices that test mineral content. How would I look into testing for parasites?

Make like the medieval times, always be drunk.

“A glass of water when Norton accidentally refunded you 4000USD instead of 400”

kinda behooves one to filter then, huh?

pond water? yes, don't drink unfiltered unboiled pond water.

Tap water? unless you live in developing countries like the USA, you don't need to worry about it, it's already treated before entering your home.
- memes aside, it's treated here.
