do you think that PE should be an elective course (one that students can choose to take), or should it be required? What about health class? Tell me your answer for each, and then give a few reasons why you chose that answer.
Answers
Answer:
I think it should be required. Since it can help encourage a healthy life style, it can help prevent you from getting as sick (since physical activity can help increase your immune system, and help reduce the risk of certain diseases like heart diseases.
However with health class I think it should be elective. Since not everyone will need to know about health, like if you become an engineer health class will not help with that.
