Los Angeles: Actor Liam Hemsworth says he would give up anything to pursue his passion for surfing. The "Independence Day: Resurgence" star said that surfing is his "favourite" thing in the world, reports femalefirst.co.uk. "I grew up surfing and surfed competitively until I was 18. Surfing is my favourite thing to do in the world. I would rather do that than anything. If I could travel around the world and surf for a living, I would," Hemsworth told Men's Fitness magazine. However, the actor has been unable to ride the waves since suffering a back injury last year. "I injured my back pretty badly surfing last year, and I haven't managed to do it since then. It is killing me. I grew up doing it, it is what I love to do when I'm not working. I skate-boarded for the first time in a while a couple of days ago but I have dreams every night where I'm surfing," he said.
