The new progress of development of new medicines to cure illnesess has made more people healthier today than 100 years ago. Now that we have better medications progress brings more happiness into peoples lives because relatives or either friends or anybody are dying. I think we have alot of new illnesses caused by all different ways. For example some people may live in a house with little shelter so that gasses fluids and pollution in the air gets in their house. So when they sleep they inhale it. Also the house might have holes in it which allows animals, bugs or any other creature like a tick in which could suck your blood or anything else. That might cause you to get sick. Another example, there are alot of diseases that infants, children, adults, and elderly people have. Those are very contagious. I think the development of new medicines that have cured new illnesses have made a big change in people's lives.
