When you hit your elbow against something, but that specific point of your elbow

it’s…called your funny bone…

that gif tho 

It’s not a bone actually- it’s a nerve that is exposed, specifically the ulnar nerve. The reason it feels so weird to hit it is that it’s not designed to deliver pain signals, so when you hit it it just wiggs out and sends Garbage signals to the brain, and the brain is just like “uh, dude- Ulnar, what the hell is this garbage?? You’re supposed to curl a finger and a half, and move some muscles in the forearm, why are you sending me this crap? How am I supposed to make this into sensory output?”
And the Ulnar nerve is just like “dude dude dude, brain- what the hell is going on?!?”
And the brain goes- “idiot. Fine. You’re on fire, freezing and being electrocuted. Happy?”
And the Ulnar goes “holy crap brain!! I’m on fire, freezing and being electrocuted! What am I going to do!!??!”
And the brain says “you’re an idiot ulnar. A damn idiot.”

This is how human anatomy should be taught

dihydrogenmonoxideawareness:

Why would anyone want to consume it!?

I teach my 7th graders about the dangers of dihydrogen monoxide.

I bring in a graduated cylinder of it and we talk about how it’s used in nuclear power plants and gmo crops. How inhaling even the small amount I’m holding can lead to suffocation or even death. It’s found in vaccines and cancer cells, but also in infant formula and pet food. It is a huge component of acid rain, can cause severe burns, and has been found in places that were thought to be the most pristine and unpolluted locations on earth.

We talk about how there are little to no regulations on this chemical. No bans, no warning labels, and most manufacturers don’t even have to disclose their use of it in their products.

My students are outraged. We talk about what we can do. Create posters and flyers to spread awareness. Contact our senators with petitions to ban DHMO. Spread this information all over social media.

Then I explain that the real problem with dihydrogen monoxide is that….when I am thirsty…there is just nothing else as refreshing, and then I watch their looks of absolute shock and horror as I drink the entire vial down.

I. Fucking. Love. This.

This is how misinformation works. How propaganda works. How manipulation works.

may our education be stronger than fake news

Amen.

To those who don’t get it:

“Dihydrogen monoxide” is the chemical name for water, AKA H2O.

another important element of understanding the joke is understanding how pH levels work

yup.  that’s a higher number alright.

i.e. why when you or someone else gets stabbed or impaled, you should leave the object in the wound until medical help arrives.

THIS. RIGHT HERE. This is an amazing example!!

If you take the thing out, they’re going to bleed a lot more.

SO. DONT.

News Flash from the Medical Help ™ — we don’t touch it either! Unless the object they’re impaled with is literally too big to fit in the ambulance, We. Don’t. Touch. The. Thing.

The only people qualified to Take-The-Thing-Out are surgeons. End of story.

Okay, but for the love of God, please, PLEASE, if you did, if you panicked and took the thing out…. DON’T…. PUT IT BACK IN.

Or else, congratulations, you just stabbed them AGAIN. I reeeeeally shouldn’t have to say this guys, but I do.
