Do You Have Good Computer Ergonomics?

Explanation
The statement indicates that the person's hips are always in contact with the back of their chair. This suggests that they are sitting with good posture, as maintaining contact with the chair provides support to the lower back and promotes proper alignment of the spine. Therefore, the answer "True" is correct as it aligns with the statement provided.

Explanation
The statement is false because ergonomics is not derived from Latin. The word "ergonomics" is actually derived from two Greek words: "ergon," meaning work, and "nomos," meaning laws or rules. Therefore, ergonomics refers to the study of designing and arranging things in a way that enhances human efficiency and comfort in their working environment.

Explanation
The statement is asking about the position of the elbows while using the keyboard. The correct answer is "True" because it is recommended to keep the elbows bent at a 90-degree angle to the keyboard to maintain proper posture and prevent strain or discomfort in the arms and shoulders. This position helps to reduce the risk of developing musculoskeletal disorders associated with prolonged computer use.

Explanation
The statement is suggesting that the activation force on the mouse should be small or not require much pressure to click. This is likely because a large activation force can cause discomfort or strain on the user's hand and fingers, leading to potential injuries or fatigue with prolonged use. Therefore, it is preferable for the activation force on the mouse to be small, ensuring a more comfortable and user-friendly experience.

Explanation
This statement is false. It is not accurate to say that your legs should never be bent. In fact, bending your legs is a natural and necessary movement for many activities such as walking, running, sitting, and squatting. Bending your legs allows for flexibility, stability, and proper alignment of the body. So, it is incorrect to say that your legs should never be bent.

Explanation
Bending the neck to see the screen can lead to poor posture and strain on the neck muscles. It is recommended to keep the neck in a neutral position and adjust the screen or use a stand to bring it to eye level. This helps to maintain proper alignment and prevent discomfort or injury.

Explanation
The statement is "Our computer labs have perfect ergonomics." The word "perfect" implies that the computer labs have an ideal or flawless setup for ergonomics. However, it is highly unlikely that any computer lab would have absolutely perfect ergonomics, as individual preferences and needs vary. Therefore, the statement is most likely false.

Explanation
Taking short, frequent breaks is more effective than taking long, less frequent breaks because it allows for better productivity and improved focus. Short breaks help to prevent mental fatigue and maintain concentration levels throughout the day. They provide an opportunity to recharge and refresh the mind, leading to increased efficiency and overall performance. On the other hand, longer breaks can lead to a loss of momentum and make it harder to get back into a task. By taking regular, shorter breaks, individuals can optimize their work and achieve better results.

Explanation
Resting your wrists on the edge of the laptop is not recommended as it can lead to discomfort and strain on the wrists. This position can cause poor ergonomics and increase the risk of developing conditions like carpal tunnel syndrome. It is advisable to use a wrist rest or maintain a neutral wrist position while typing to prevent any potential injuries or discomfort.

Explanation
This statement is false because tennis elbow is not exclusively caused by playing tennis. Tennis elbow is a condition that occurs due to overuse or repetitive stress on the muscles and tendons of the forearm, specifically the extensor tendon. While playing tennis can be a common cause of tennis elbow, it can also be caused by other activities that involve repetitive gripping, such as painting, typing, or using tools. Therefore, it is incorrect to say that you can only get tennis elbow from playing tennis.
