One of YouTube’s smartest academics is getting physical. CGP Grey‘s latest video explores the nocebo effect, and he begins by attempting to give each viewer a headache.

I don’t want to give anything away, so you should probably just take a look for yourself:

Pretty cool, right? Of course, everything CGP Grey puts on YouTube is extremely cool, so this video isn’t out of the ordinary in that regard, but it’s still quite remarkable that the American-born Londoner managed to hex us through the Internet.

Viewers seem to agree that this video, Grey’s first in two months, is one of his best. They’ve already provided it with more than 1.8 million views only two days after its release, putting it on a trajectory to become one of Grey’s most viewed efforts.

Where do you think the nocebo video ranks among Grey’s body of work? Did he successfully affect you with his mind powers? Did this video finally convince you to go over to Subbable and implore Grey to take all your money, please? All these questions are worth considering.
