There has been arguing over technical development's advantages or not. I absolutely agree that this problem is harmful to our health. Advocates contend that inventions like the computer and television would be more helpful for making our lives more efficient and easygoing. They believe that technology development will be our alternative option in the future. Hence, these gadgets give us ways to improve our health, like using apps. For example, we can use the apps to calculate our heart rate. Moreover, some apps would be useful when we face emergency situations by calling the police or hospital.
