In today’s world using computers is a necessity for the majority of people but not many people actually consider the medical consequences that working with computers can cause, such as:

- muscle pain

- damaged eyesight

- bad posture

- arthritis

* Sitting at a computer for long periods of time can take a toll on your body. By not sitting with the correct posture, it is easy to end up with back pain, neck pain, knee pains, and a tingling of the hands and fingers.

Make sure that your chair is at the right position to help prevent back problems in the future.

It's very important to stand and walk around while sitting for 30 minutes, because prolonged sitting can cause pelvic nerve pain. Also, years of prolonged sitting can lead to other health problems. That 1-2 minute break after 30 minutes isn't that bad when it helps to prevent other pain and possible serious issues.

Avoid using excessively wide wrist rests, or wrist rests that are higher than the space bar of your keyboard.

A way to stop eyestrain is the 20, 20, 20 rule. Every 20 minutes look at something 20 feet (6.1 m) away for 20 seconds.

Computer rage is the expression of anger and frustration that occurs while using a computer or similar device.

- thumping the keyboard

- punching the monitor

- slamming the mouse on the table

- TV viewing is the most common sedentary behaviour for adults, in their leisure time?

- Adults should spend at least 30 minutes a day on physical activity?
