Actor Liam Hemsworth admits he loves the adrenaline rush he gets when he attempts risky tasks like extreme surfing.

He also challenges himself to ride bigger waves, and says "the fear of dying" is "part of the fun in it".

"The adrenaline you get from surfing big waves. I have seen a shark before. You get the worst wipeouts when you're not expecting it," femalefirst.co.uk quoted Hemsworth as saying.

The 22-year-old, engaged to singer Miley Cyrus, also says he is addicted to food and he found it difficult to change his diet for his role in The Hunger Games.

"It was tough because I'm an eater. If I have one addiction in life, it's probably food. You gotta get, like, 24 Krispy Kreme's and eat all of them. I lose my mind. Go crazy. Krispy Kreme fever," he said.
