What do YOU think makes someone cool?

Researchers think they've worked out which personality traits makes a person 'cool'.

They asked 6,000 people from 12 countries to think of someone they thought was cool and not cool and then rate that person's personality.

According to the study published in the Journal of Experimental Psychology the six qualities are: Extraverted, hedonistic, powerful, adventurous, open and autonomous.

In other words, it's someone who is outgoing, lives for fun and is independent, making their own decisions.

But we want to know what YOU think makes a person cool.

Is it the way they interact with people? Is it how they dress? Maybe there's a celebrity you think is really cool - let us know in the comments below!.

The history of cool

Jazz musician Miles Davis recorded an album called 'Birth of the Cool' in 1957

The word 'cool' started out as a way to describe temperature - not too cold and not too hot and it can still be used in this way.

By the 16th Century, it had evolved to also describe a person if they were calm and collected.

The modern use of the word cool came from black jazz musicians in the 1940s.

It was used to describe a person who was rebellious or charismatic and who helped to create social change through things like art or protests.

Words continue to evolve over time. You might not even use the word cool - maybe you use sick, sigma, or gucci instead.

Don't forget to let us know what you think makes someone cool in the comments - you could even tell us what is totally uncool.
