The face-down generation(一代)

If you were born in the 2000s, you are called the oh-ohs. The 21st century. That would make you young, creative, connected, world-wide, and no doubt smart. Maybe good-looking, too. Right? But what do other people think about your generation?

Some adults worry that you're more interested in the screen in front of you than the world around you. They think of you as the "face-down generation" because you use your phone so much. They wonder how you will deal with school, friends, and family.

Other adults worry that today's youth are spoilt (溺愛) and don't want to face the challenges of adult life. Many children born in the 1990s and 2000s were raised by "helicopter parents". They were always there to guide and help their children with a busy program filled with homework and after-school activities such as dancing, drawing, or sports. With parents who do everything for them, today's youth seem to prefer to live like teenagers even when they are in their 20s or 30s.

Does the face-down generation need a heads-up? Well, probably not. The fact is that many of today's teenagers are better educated and more creative than past generations. They seem to be willing to become leaders. More young people than ever volunteer to help their communities. There are also brave young people such as Malala Yousafzai, the teenager who won the 2014 Nobel Peace Prize for pushing girls' rights to go to school.

So if you're one of the oh-ohs, there's reason to be hopeful about the future. Things are looking up for the face-down generation. Chances are that you do great and laugh out loud.

Before there was the written word, there was the language of dance. Dance expresses love and hate, joy and sorrow, life and death, and everything else in between. 1. We dance from Florida to Alaska, from north to south and sea to sea. We dance at weddings, birthdays, office parties and just to fill the time. “I like dancing.” says Lester Bridges, the owner of a dance club in Iowa. “I can’t imagine doing anything else with my life.” Bridges runs dance classes for all ages. “Teaching dance is wonderful. 2. It’s great to watch them. For many of them, it’s a way of meeting people and having a social life.”

3. “I can tell you about one young couple,” says Bridges.

“They’re learning to do traditional dances. They arrive at the class in low spirits and they leave with a smile. 4.”

So, do we dance in order to make ourselves feel better, calmer, healthier? Andrea Hillier says, “Dance, like the pattern of a beating heart, is life. Even after all these years, I want to get better and better. 5. I find it hard to stop! Dancing reminds me I’m alive.
