I agree the the saying \"prevention is better than cure.\" It is said that modern medicine is reactive rather than proactive. When you get sick, you seek medicine. Think how inefficient that model is. It is better to prevent disease rather than finding resolution after they occur. The responsing here is similiar to why you change the oil in your car rather than wait to fix an impaired engine. This is why we try to vaccinate or inoculate against as many viruses as possible. Prevention care also has the potential to control risk factors, thereby reducing the prevalence of costly chronic services. The saying is not only true in medics, but true in many other areas. For example, it is a well-known fact that if we run an AC with a fan, within a short span the AC will slowly accumulate copious dust.
