Answer:
for -
it could save millions of lives. going to school, everybody spreads everything around, if somebody catches something you're more than likely to get it too.
able to spend more time with family. spending time with your family is important and healthy for good relationships/friendships and most kids/teens dont get enough time with there family due to being at school for 7 hours each day then coming home to do homework.
you're able to have a little extra "you" time which we all need now and then. if you dont take time for yourself you can get in a really bad habit of not taking care of yourself and that'll affect your physical health AND mental heath.
against-
kids could skip school way more easily. kids/teens could not find school as important because they're not actually getting up and going which can put you on truancy. then you'll have a bunch of legal stuff to deal with which is never fun
mental health could go way down. by not seeing your friends everyday like you normally did and if you're just staying in your room all day sleeping, you can get into a really bad routine and without a structured routine your mental health will be highly affected.
nutrition will most likely be highly affected. at school you get food and are forced to take one fruit and one vegetable, some people might not want to get it but when its in front of them, they normally eventually eat it and if you're home without that push of eating healthy then you'd just eat junk food or not eat at all and then your physical health would lower and you'll be more prone to getting sick
i think they should leave schools closed. both of these options some bad issues or be dangerous but i think that opening schools would be highly more dangerous than not due to the fact that everything gets spread around and more people would be in danger.
