Gotta Go... FAST

It's rude. You're making someone take their time to read something you couldn't bother to write. You're telling them they were so unimportant you couldn't be bothered to actually take the time to say something yourself. And frankly, you're lying about it while you're at it.

Your brain is an incredibly energy-intensive organ. It makes up approximately 2% of your total body mass, but at rest it's using 22% of your total energy intake. The only thing that uses the same percentage of energy is all of your skeletal muscle (which is about 40% of your total body mass), with the liver (about 2.6% of your total mass) close behind at 21% (Aragon et al, 2017).

And that's how much energy it's using at rest.

That's the baseline.

So if you're doing lots of intellectual labour, your brain - which already has disproportionately huge energy demand - is going to use even more energy to keep up with the work. That's why you feel so wiped/drained/like you're out of spell slots after high intellectual demand - because your brain is an organ, and you've just done a lot of high-energy work with a high-energy organ.

Arakawa realized the burgeoning youth of the early 2000s wasnt interested in another plucky spry optimistic young shonen protag. Instead she gave us a short ugly egotistical asshole smarter-than-you atheist with so much money and power that people could no longer best him in arguments by telling him “dude shut up ur literally like 12″ 

Five pages in we’re told Edward’s famous and rich and powerful. Five more pages and he’s calling some girl stupid for thinking God exists. Five more pages and he’s proven right. Five more and he’s kicked an evil priest’s teeth in. And no one can tell his mom on him.
