The secret of being cooool; SCIENTISTS CRACK CODE.
YOU know it when you see it but often you just can't put your finger on it.
For years experts have tried to work out what makes people cool.
Now two New York psychologists reckon they've discovered the secret... all because of a row over Steve Buscemi, the bug-eyed star of Reservoir Dogs dubbed king of cool by movie fans.
Ian Hansen could see why Buscemi was cool, but his pal Ilan Dar-Nimrod could not. So the pair started an academic investigation to find the nature of coolness with the help of 350 students.
They were asked what qualities made people cool then rated friends with their own coolometer.
"We wanted to tease apart coolness and social desirability," said Dar-Nimrod. They unearthed totally different kinds from hot, sexy, risky and rebellious cool to friendly, successful, trendy and funny cool. We applied their findings to some famous faces. And heyyyyyyyy, as that cool Happy Days dude The Fonz would say, we nailed their coolness rating.
