My oath, Hippocrates is still relevant

In many ways, Hippocrates was ahead of his time, as his teachings are relevant today and are the roots of modern medicine. 

Hippocratic medicine moved away from supernatural thinking, such as disease was a punishment for sin, towards a more rational approach to understanding the human body. This was by providing more ‘scientific’ reasons for ailments, making diagnoses and prescribing lifestyle advice such as diet, exercise, hygiene and sleep. Hippocrates didn’t have the science to back his approach.
