Yes, they're sort of emotional.

We get them in response to the chills, very strong emotion.

And I guess that's similar to terror.

Again, it serves no purpose in us.

Why should goosebumps...

help us in any way when we feel moved by music or what someone says or extremely emotional.

It's just, again, something inside us that we've inherited from our ancestors.

Yes, our face's left side is more emotionally expressive than the right side.

In other words, the left side of your face is better at showing feelings.

And this hugely influences how you show yourself to the world.

For example, when you pose for a selfie, you will very lightly angle your head to show more of the left side of your face to the camera.

In fact, research shows that selfies on social media are much more likely to be left-sided than right-sided.

And also, interestingly, pictures of left-sided faces get more likes on social media than right-sided snaps because the left side of the face is more emotional.

And this is all to do with the way your face's muscles are wired.

Muscles that make expressions on the face are controlled by the opposite side of the brain.

So the left side of the face is mostly controlled by your brain's right side.

And that right-sided brain happens to be the more emotionally competent side of the brain.

So hence, the left-sided muscles are more emotionally competent, more emotionally expressive.

And this left-sided bias for emotion is, as I said, shapes the way we look at the world and the way we see the world.

It's one reason why new mums cradle their baby with its head on their left side so that the baby can look up and see the left side of her face.
