According to the Oxford New English Dictionary a doctor is a person who is qualified to heal an ill person. Today medical professionals have come a long way. Once seen as witch doctors-cum-magicians, now they stroll the corridors of high-tech hospitals with regal airs. In a dehumanising technical age, where diseases and patients are seldom seen in their unity, doctors in their pursuit of self and skill advancement convince others as much as themselves of their proficiency in the field of healing with the help of four invaluable tools - drugs, devices, drips and degrees.
