A surgeon often works in an area where not many people know. They work behind a perimeter of a sterile area. Time is not the limit. What limits them is their dexterity in handling the difficult case. They work solo as well as a team. In the academic medical center, where we train future-surgeon, the operating room may become an operating theater. The surgical resident will gather in the theater to see and learn from their super-ordinate about an interesting surgical case. These multi-faceted photos reveal their performance at the hidden perimeter where the demarcation between life and death lies. There are 3H that defines their works: Hands, Head, and Heart.
