“Man know thyself” those were one of the first powerful lesson I learnt from undergraduate lectures, “Cogito ergo sum” is a Latin philosophical proposition by René Descartes usually translated into English as “I think, therefore I am”. Our society and educational system has thwarted the major essence of those words, every job profession has its role/importance and serve their different purposes in the society. A fashion designer for example cannot serve the role of a medical doctor.

Before the discovery of modern medicine, life was short-lived for humans. Then medical practice changed into an organized profession, and humans experienced a significant improvement in the quality of life. Aided by modern scientific innovation, the boundaries of medical technology extended to unimaginable limits.

1. Saving Lives

In certain circumstances, a doctor can mean the difference between life and death. Accident and violent crime victims and soldiers wounded on the battlefield know this because their lives depend on the skills of trauma surgeons. People who suffer critical injuries need a doctor to attend to them quickly because delaying treatment might simply mean death.

2. Extending Life

Doctors are responsible for increased life expectancy and improved well-being in society. People who survive diseases such as cancer usually owe their survival to doctors, whose skills and dedication are vital for their cure. Modern medical technology coupled with doctors’ care can give persons diagnosed with terminal illnesses hope of living longer.

3. Humanitarian Work

Doctors perform humanitarian work in society. Some advocacy groups on health issues, such as hypertension and cancer, draw membership from the medical profession and help disseminate information about how to avoid so-called lifestyle diseases. Doctors may work as volunteers on missions ranging from providing care to disaster victim.

4. Controlling Epidemics and Conducting Research.

When disease outbreaks occur, information provided by doctors can help contain the epidemic. They also check the spread of disease by alerting the public to factors — such as poor hygiene and risky behaviors — that spread disease. Doctors also work alongside researchers to find new cures for diseases, running drug tests on consenting patients.
