Health is very important for every person. Everybody wants to be healthy and active. But in spite of that a lot of people nowadays have different illnesses and other health problems. I take care of my health because I like to feel well. But sometimes it seems that everyone all around me is ill, so it’s very easy to get sick. Sometimes I’m tired or stressed and I have a headache. So I have to use an aspirin or some other pain killer.
