Human beings are smart. However, it seems that people are gradually losing their smartness as smartphones become more and more important assistants in their lives, reported news website Record Japan on Oct. 22. As we rely too much on technology instead of our brains, many people have lost three basic abilities, said the website.

The first skill many people have lost is remembering phone numbers. Because phone numbers are stored in smart phone contacts, there's no need to dial a number or look at it again.

And some people may also have lost their sense of direction because navigation apps can guide people anywhere they want to go. These apps can even find shortest routes for you and avoid traffic jams. But the worst lost skills may be social ones, meaning that some people are becoming socially inept(无能的）. People often bury themselves in their smart phones. As we're too addicted to what's happening in the virtual world, some of us have lost conversational skills and sometimes can't even tell whether a person is happy or not.

In August, researchers at the University of California, Los Angeles, studied 51 students aged 11 and 12 who had over five hours' screen time every day. Their task was to tell the emotions of 48 pictures of faces that were happy, sad, angry or scared. The children made an average of 14.02 mistakes at the beginning. But after a five-day camp without electronic (电子的) products, they made only 9.41 mistakes on average. “If you’re not practicing face-to-face communication, you could be losing important social skills,” concluded professor Yalda Uhls from the research.

Luckily, people still have a chance to get these abilities back. You should try to keep your parents' numbers in mind for emergencies. You should also pay more attention to street signs and stores, which will help you to draw a mind map and stop you from getting lost. And the easiest solution to social skill loss is to take a break from electronic devices because we are social creatures. We need device-free time.
