When I got a headache, she soaked a rag in vinegar and tied it around my head and it worked.
That's sweet, but your grandma wouldn't be able to perform heart or brain surgery. You need proper medical education for that.
I am talking about the useless bs like geography, history, arts, music, and math
Thank God people like you weren't deciding about the development of humanity/civillisation or the world would be boring as f*ck and filled with ignorant morons lol
Btw, a lot if not most of the stuff you're using was designed by someone who more likely than not graduated from some kind of art course. Including the look of that Jaguar car which you like so much:
That designer graduated from a two-year course in Automobile Design at the Royal College of Art.
Of course, we could all live without nice looking cars, clothes, furniture, films, computer games, music, paintings, etc., but since we can and it gives joy, entertainment and pleasure to so many people then why wouldn't we have all of that? Because some grumpy, boring old man (you) says so?
