I remember back in school, my professor told us that yawning was meant to keep us alert. This is why other animals also yawn. The idea being that yawning would force us to refocus or wake up when we are suppose to be alert or on watch. When someone does this, others nearby would also do so in the attempt to stay awake as well. This is mostly instinctual.

Koalas have finger prints to and they’re very close to human ones

My takeaway from this video:

*Laughter is the best medicine*

In my mind, consciousness is pretty much just a manifestation of multiple pieces of information and brain processing coming together. I don't think it exist in any physical way, it is more like an experience.

Day 13 of requesting infographics to cover: you vs terror Billy

I don't see how Infographics isn't a science teacher yet.

When he said why do men find farts funny I giggled and I felt like he triggered something built into every man 😂😂🤦

The appendix I have heard is kind of a refuge for microbes that helps us restore our microbiome after something like an infection or food poisoning.
I have heard that people who have it removed tend to have more digestive tract issues and take longer to recover, although I have no idea if any of this is true in any way.

[-You-need-a-hug-]

This is true
Him: since I said the word yawn you may be doing it right now
Me: **terrified to move cause I just yawned**

I've noticed it's hard for mosquitoes to bite my arms because of the hair.

Remember the guy who had a concussion, woke up and was able to play the piano with precision and skill even though he had never touched a piano before?

We blush when our blood pressure goes up, think about it, we blush when we're embarrassed, shy, lying, uncomfortable, all those things gets your blood moving

A lot of these questions they ask in this video actually has answers. It drove me nuts answer a lot of these questions to myself.

About our strength, ive read that its because we evolved as endurance creature, and these endurance muscle fibers slowly replaced twitch muscle fibers

In the case of the appendix; studies have shown that after a "cleansing of the gut" (diarrhea) bacteria levels return to normal faster in people who have their appendix, so it's like it keeps an emergency supply of your gut bacteria which is kinda cool.

I yawn after yawning all day. i even yawn after that. To make matters worse, i've yawned a few times in the process from thinking of and writing this comment. 😮😲😲😲😮😩

10:44 "Honey, let's share some microbes."
The partner: "wtf?"😂

The fingerprint thing is a good question honestly..I've NEVER really thought bout it before

[yosiahw]

Honestly I think that the human brain is so complicated that I can't even begin to understand it. There have been cases where people have had concussions and woke up speaking new languages perfectly when they had no ties to the countries that speak said languages.

I find that to be such a beautiful thing: we are gifted with so many questions that science will never run out of new things to reveal.
