Usually, people want to "look cool" in their photos. But how can you look cool? What do you think being cool is? To look cool, many people always don't smile or show any f. Is it true?
Caleb Warre, a professor(教授) from America, says a lot of people a with that. So models(模特儿) don't usually s in shows. Some actors and singers also think that way.
But a new study by Warren tells us something d. The study finds a nice smile will help you look cool in a photo. In the study, Warren shows some stars' photos to a g of people. There are two photos of each star—one smiling and the other not. Which one is cooler? Most people like the smiling ones better. The smiling photos are cooler! Even if you are just an o person, a smiling face makes other people feel good.
So, can you get something from Warren's study? Just smile, please!
