Medical
The medical world is an ever evolving community that aims to constantly improve human health with a variety of methods and practices. These can range from preventative medicine such as vaccinations, inoculations and lifestyle advice to treatments of illnesses and diseases. The medical world has changed a lot since the start of mankind and through the ages with wars, famine and other obstacles that have faced the human race it has managed to develop into what it is today. A combination of medical technology with the expertise to implement such technology has led to great advances in the field.
Perhaps it was during Ancient Greek and Roman times that some aspects of modern medicine have their origins. Figures like Galen and Hippocrates introduced methods that have fed into modern practices (modern doctors still have to pledge a Hippocratic oath before they can practice medicine) as well as suggested theories that have since been discounted. Though it was not all correct, their influence has still lived on as well as those suggested by later researchers and medical practitioners. In the last couple of hundred years the great advances have come from the likes of Andreas Vesalius, Edward Jenner, Louis Pasteur and Alexander Fleming.
