OPINION PARAGRAPH

Should we really need medicine or not?

Sometimes, we strated to take medicine even when it is not necessary. That is known as placebo effect.But, how affect placebo to our lives? Is it real or not?

I will tell you my grandfather's example. He used to have some medicines to sleep well but the doctor didn't prescibe him more (because he doesn't need to take them). As he starte to complain, my mother bought some medicines without effect and gave them to him. Next day, we asked him how he had slept and he told that perfectly. As I have told, medicines are not always necessary.

So, we can see that placebo effect exists on some people, mostly on old people.
