Get kids away from the telly and doing something useful.

It’s official: TV makes kids fat. According to a recent study, adults who had been avid TV watchers as children were more likely to be over­weight, to smoke and to have high cholesterol.

“Children should watch no more than two hours of TV a day to pro­tect their future health”, the study warned, adding that parents should “lead by example” and turn the TV off.

But agreeing and doing are too different things. TV is a great help to many parents, taking away some of the daily pressure of entertain­ing children.

Even if the benefits are often all too short-term, with kids often ending up bored, listless, uncommunicative and grumpy after just a few hours of television viewing, today’s busy urban lifestyles often allow for few alternatives. Except, that is, for computers. Computers don’t replace the need for children to get out of the house and take good exercise, but they do offer a ‘lean forward’ experience that is much to be preferred over TV’s passive, ‘lean back’ mode of viewing.

The body language says it all. At a computer, children can get a re­action. They can be mentally active and emotionally responsive when engaging with quality computer software or emailing friends.

Good computer content can enable children to engage actively, to be creative and to grow intellectually. Of course children need to be physically active and every day they should be outside playing, cy­cling, and running about at some point. But there are times when it is necessary to be indoors and if there is a computer to hand, well let’s see children use it to best effect. With
a little help from parents — or grandparents — the computer becomes a really valuable tool.
