     "The age of melancholy" is how psychologist Daniel Goleman describes our age. People today experience

more depression (feeling of sadness) than older generations, though the technological wonders help us every

day. It might be because of them.

     Our lifestyles are increasingly driven by technology. Our days are filled with phones, computers and the

Internet. There is a constant need to check for texts and emails, to update Facebook, MySpace and Linkedin

profiles and to acquire the latest notebook or 3G cell phone.

     Are we being served by these technological wonders or have we become enslaved by them? I study the

psychology of technology, and it seems to me that we are sleepwalking into a world where technology is

severely affecting our well-being. Technology can be hugely useful in the fast-paced modern living, but we

need to stop it from taking over.

     For many of us, it is becoming increasingly difficult to control the impulse to check our inbox yet again or

see whether the headlines have changed since we looked last time. Our children are in a similar position. In

many homes, the computer, with which we work and play, has become the centre of attention.

     How does this arise, and what is it doing to us? People who place a high value on material goals are

unhappier than those who are less materialistic.

     Our culture also Constantly reminds us that time is money. This indicates a need for total efficiency (效

率), which is the reason for us to allow laptop computers and mobile phones to blur the separation, between

work and home. As one unhappy human resource manager in a high-tech company 'put it, "They gave me

a mobile phone so they can own me 24 hours a day, and a potable computer, so my office is now with me

all the time-I cannot break out of this. pressure." Sound familiar?

     Psychologists generally believe that the lack of a clear separation between work and home greatly damages

our relationships with loved ones. It also makes us quite likely to focus on the here and now at the expense

of long-term goals.

     Modern society is in danger of exchanging standard of living for quality of life. We need ways to help

recover those increasingly large parts of our lives that have been controlled by technology, to regain mastery

over technology and learn to use it in a healthy and positive way.
