When a man goes through six years training to be a doctor he will never be the same. He knows too much.

Summary

This quote suggests that the experience of going through six years of medical training fundamentally changes a person, particularly in terms of knowledge and understanding. The extensive education and exposure to various aspects of medicine cause an irreversible transformation in the individual. They become aware of a vast amount of information and gain a deep understanding that impacts their perspectives, actions, and decisions in ways that cannot be undone.
