If you're spending hours in front of the computer, doing homework, e-mailing friends, and surfing the INTERNET, make sure you're taking the right steps to minimize physical strain on your body.

• Try to put as little strain on your back, neck, and wrists as possible.

• Adjust your chair so that your feet rest comfortably on the floor. If you can't adjust the chair, get a foot rest or use a thick book (a science textbook maybe?)

• When possible, use a chair that offers lumbar support. If you experience back or neck cramps, get a back rest (available at any drug store). The backrest should conform to the natural curve of your back.

• Your keyboard should be at a height that lets your lower arms be parallel to the floor, your elbows bent at a right angle. If necessary, get a key board tray.

• Your wrists should be slightly higher than your elbows.

• The top of your screen should be at eye level (this will prevent you from straining your neck).

• Don't forget to rest your eyes. Look away from the screen regularly.
