Straighten Out Your Cyberkids

A study at Australia's Curtin University of Technology found 60 percent of kids using computers at school showed signs of repetitive strain injury. Here are some desk exercises.

1. Stretch your arms above your head and spread your fingers. Then lower your arms so they're straight out in front. Hold for a few seconds.

2. Push the bottom of your right palm against the top of your left palm, so you feel a stretch along the underside of your left forearm.

3. Sit with your back straight, look over your right shoulder, then your left. From the centre, nod slowly three times. Turn your head in a "no" motion three times, then stretch as if laying your hed on each shoulder.

4. Keep your hips forward and turn to look behind on each side, with your arm across the back of the chair, stretching your back.

5. Push your chin forward to stretch the jaw and neck.

6. Sit and roll each shoulder forwards and around then back and around. Lift each shoulder to your ear and down.
