Today on something you should know, there's a really boring 18 minute YouTube video you should watch

because it may be the best thing that happens to you today. Also, there are several things you would think scientists should probably know that baffles them completely.

Well, the thing that I think shocks most people is the fact that 95% of the universe is missing.

We actually only know about 5% of the universe, which is the kind of stuff that we're made of. And this is a such a longstanding mystery.

Then there are many words you likely use when you write that you don't actually need. And do you have people in your life who make you feel bad or stupid or ignorant when you talk to them?

That's the gas light effect.

The gas light effect describes what happens to you when you begin to second-guess yourself because you've allowed another person to define your reality and to erode your sense of self, your confidence and your judgment.

All this today on something you should know.

I just learned, discover credit cards do something pretty awesome. At the end of your first year, they automatically double all the cash back you've earned.

That's right. Everything you earned doubled. All the cash back from eating at your favorite soup-dumpling restaurant doubled. All the cash back from that trip you sort of learned how to snowboard. Also doubled.

And the best part, you don't have to do anything ridiculous to get it. Oh, discover does it automatically.

Seriously, though, see terms and check it out for yourself at discover.com slash match.

Something you should know. Fascinating intel. The world's top experts and practical advice you can use in your life today. Something you should know with my carothers.

So I just finished watching. Well, I didn't finish it. I watched most of it. It's an 18-minute YouTube video on how to fold towels.

And it's narrated by a woman who barely speaks above a whisper. And about two million people have viewed this thing. And it's not because people really need to know how to fold towels.

You probably mastered that a while back in your life. Instead, people watch it because an increasing number of people report experiencing something called autonomous sensory meridian response or ASMR.

It's a whole body tingling sensation that listening to a soft monotonous voice can trigger. ASMR is a neurological experience that causes people to experience what has been termed a brain orgasm.

It's a tingling pleasurable sensation similar to goosebumps that begins at the head or neck and works its way throughout the body.

The most common triggers of this sensation include educational videos like how to fold a towel, having your haircut. Yeah, I've had that. I've had that kind of tingly sensation when I've had my haircut.

Feeling empathetic, enjoying music or art, listening to slow, enunciated speech, and experiencing close personal contact.

It feels so good that people keep rewatching this incredibly dull video just to have that experience over and over again.

What's interesting is that science doesn't recognize this as a real thing. It doesn't ever appear to have been studied or written about scientifically. And it doesn't happen to everyone.
