I'm a junior and a senior. Now, as you said, many people become nerds when they have computers. They have been sitting in front of the computer except for class and going to the toilet. This state is hard to change. Like me, I hope you turn off the computer at 10: 30 every day, go to bed to play with your mobile phone and read books, fall asleep immediately, then wake up in the morning and go outside to breathe the air. You will find that the morning air is what you really need. I hope you are happy!
