Look, we could learn things by “reading books” or “taking classes” or whatever, but wouldn’t it be more interesting to just scroll through Tumblr until we found some posts that taught us things?

That’s what I do, and now I have an absolute wealth of dubious, fascinating knowledge with which to annoy my friends at parties!

Check out these twelve incredible topics I learned all about from the Humans of Tumblr.

12. Psychiatry and diagnostics

Back in my day, we didn’t have all this dark matter! You kids and your quantum physics!


11. Economic theory

Turns out very few of us are happy about anything ever but we all need money. Who knew.


10. Psychology and mortification

This is literally why I cannot watch the first couple seasons of The Office.


9. Currency and debt

It’s almost like we have a system designed to make money trickle up.


8. Personal motivation

The voice in our head has much to teach us, and I don’t wanna hear a word of it.


7. Mexican-Japanese history

I smell a smash hit HBO series in the works.


6. Biblical literature

Blessed are the meek, for they will have righteous gains.


5. Marketing and sexuality

Come on Barbie, let’s go party.


4. Photography and cultural etiquette

I would buy rice from this man any day of the week.


3. Literary analysis

Once upon a time…


2. Locomotion and human enterprise

Can’t stop won’t stop.


1. Grammatical structure

I’m going to need this entire post to just get out.


I think this list basically counts as some kind of undergraduate degree. You’re welcome.
