Professors literally get like $0.03 per copy of a book sold. Your professors make you buy their book because no one else teaches the class like they can. It’s their expertise that you’re paying for when you go to college to study under them. They’re making sure that you have something related to that that lasts.

They’re trained on scientific writing, and we em dashes all the time in scientific writing.

Wankpuffin is actually a specific example (given within the paper) of British vulgarity considered in this study.

Even somewhere warmer, I’m a 2 year-round, too. I just have one very cool sheet that I use in the summer.

Nothing in the Frontiers is reputable among scientists. It gets linked a lot on Reddit because it’s open access, but scientists tend to view it as essentially the not-actually-peer-reviewed equivalent of a preprint. In the past, if all reviewers recommend rejection at Frontiers, the editor would be forcibly assigned new reviewers by the publishing staff. This would continue until the manuscript would get accepted. Not sure if that’s still the same (I’ve blocked all Frontiers emails), but it’s not correct to call a Frontiers journal a major reputable journal.

The pot in my ass

If you don’t already have some form of metal that has been intentionally added to your body, my guess is that you will before you die.
