The life of a Royal seems like it's less a life in the lap of luxury and more a life constantly in the spotlight.
Things must get pretty stressful, but Prince William has a pretty healthy coping technique.
He doesn't hit the bottle, he listens to animal noises on his iPhone!
The Prince has loved Africa all his life, starting with amazing stories of adventure told to him by his mother Princess Diana.
So the sounds of Africa, the noises of the animal kingdom, help to calm and center him.
