     With the development of science and technology, most of us will comment:"Life is speeding up.

Everyone is getting unwell."

     This may sound like something someone would say today. But in fact, an unknown citizen who

lived in Rome in 53 AD wrote it.

     We all love new inventions. They are exciting, amazing and can even change our lives. But have

all these developments really improve the quality of our lives?

     Picture this, you're rushing to finish your homework on the computer. Your mobile phone rings,

a QQ message from your friend appears on the screen, and the noise from the television is getting

louder and louder. Suddenly the computer goes blank and you lose all your work. Now you have

to stay up all night to get it done. How calm and happy do you feel?

     Inventions have speeded up our lives so much that they often leave us feeling stressed and tired.

Why do you think people who live far away from noisy cities, who have no telephones, no cars,

even no electricity often seem to be happier? Perhaps because they lead simpler lives.

     One family in the UK went "back in time" to see what life was like without all the inventions we

have today. The grandparents, with their daughter, and grandsons Benjamin, 10, and Thomas, 7,

spent nine weeks in a 1940s house. They had no washing machine, microwave, computer or mobile

phones.

     The grandmother, Lynn said, "It was hard physically, but not mentally." She believed life was less

materialistic. "The more things you have the more difficult life becomes." She said. The boys said they

found less to fight over, such as their computer. Benjamin also noticed that his grandmother had

changed from being a "trendy, beer- drinking granny to one who cooked things".

     Here are some simple ways to beat the stress often caused by our inventions!

●Don't be available all the time.Turn off your mobile phone at certain times of the day.Don't

check your emails every day.

●Make sure you spend some time talking to your family.Set aside one evening a week when you

don't turn on the television.Play cards and chat instead.

●Get a low-tech hobby.Every day,do something in the old-fashioned way,such as walking to have

a face-to-face meeting instead of using the email or telephone.

●Don't worry too much about life-laugh more!
