‘Prevention is better than cure’ is an old saying. Most of our diseases are because of malnutrition. A very large number of people, now a days suffer from cardiac trouble. It generally originates from high blood pressure. It is not an infectious disease that we catch from others, nor is it a viral disease. The cause is that we do not take care of our body. We take spicy rich food and do not do any physical work. All the butter that we consume is deposited in arteries. The circulation of blood is affected as the passage becomes narrow. Poor heart has to work more. It may succumb to pressure one day. One should rather take precaution to avoid very rich diet. It would prevent heart trouble. If we practice prevention and avoid the things that harm us we do not fall a prey to them. Cure is not required. The phrase applies to other aspects of our life too. There are communal riots, political enmity, and social disparities resulting even in murders. Jealousy may result in wars at International level. These can be prevented if we have better understanding and more of tolerance. Thus prevention is better than cure in all aspects of personal, national and international fields.
