The Prince's scare was prominent while growing up, but a closer look shows off a thin line on his face. He calls it the Harry Potter scar because there are times when you notice it, whereas, on other occasions, it looks completely invisible. William was 13-years-old when a golf club hit him on the forehead while he was playing golf with a friend.

Many people could have used cosmetic surgery to make the scare disappear, but William didn't opt for such procedures. The scar serves as a memory of that golf match he had with his friends and it is often a sweet reminder of his childhood. The Prince also has another health relic he got during his two years as a pilot for Air Ambulance.

The Prince met so many sick and impoverished people that it made him depressed after he came home. He struggled with mental health issues for many years but he has finally learned to defeat his inner demons.
