text: One reason students should be forced to take at least one school activity is some students after school just go home immediately to watch television or use their phones,the reason this is a problem is because that isn't good for their heath kids, need at least a couple of hours in the sun the reason being is the sun provided Vitamin D. Another reason is students eye sight could get worse by them looking at a screen all day. The final reason is some students are addicted to using their phones, did you know that phones can cause cancer? by students doing a sport or club this can limit screen time.
