Not everything is extra good. There is a limit to the use of everything. Danger if you exceed the limit. For example, if you remove the sleep from the bed at night and press the phone in front of you, it will be late to fall asleep at night. The eyes will hurt. Will have a headache. The rays emitted from the light of the phone have a very bad effect on the eyes. It's just that I talked about the night, there are many more like this. The bottom line is to refrain from using extra phones. And someone else will be careful. Come on, you know. Thanks
