In today's era, the Internet is increasingly developed and the online game industry is growing stronger day by day. While online games are hugely popular, they also receive a lot of criticism.On the one hand, online games can not only vent their emotions, reduce the pressure of life and work, but also add to the fun of life, contact the feelings between friends.However, addiction to online games may have serious consequences.For example, it damages eyesight, consumes energy, wastes a lot of time and money, reduces the communication with people around and so on, which is not conducive to real life.So In my opinion, moderate games are good for our brain, but we should not be addicted to them.
