In 2002, an Australian man went to his friend's 21st birthday party. He got drunk, fell off some steps and cut his lip. He took a picture of his injuries and shared it with his friends online. "And sorry about the focus," he wrote. "It was a selfie(自拍). "That was the first recorded use of the word "selfie", according to some experts at Oxford Dictionaries.
Oxford Dictionaries declared "selfie". In recent years, the act of taking a picture of oneself with a mobile phone, placing the subject center-stage, has won great popularity with everyone from Britain's Queen Elizabeth Ⅱ to U. S. President Barack Obama joining in.
But the rise of selfie photography in some of the world's most beautiful, and dangerous places has also inspired a lot of risk-taking behavior, such as hanging from a tall building, standing in front of a rushing train and crossing a busy street. People who get addicted will never stop taking selfies, completely ignoring where they are. In fact, there have been several reports about people losing their lives while taking selfies. Several governments have now begun treating the selfie as a serious threat to safety, warning visitors to pay attention to the dangers when taking selfies.
"Walt Disney World is also banning selfie-sticks in its theme parks because selfie-sticks have become a growing safety concern for our guests, " Disney World spokeswoman Kim Prunty said under the new policy, and guests will be checked for the equipment during the routine bag check that happens near the parks' entrances.
