Michael Caine
Not only did this British actor join the military, but he thinks you should too. The actor has stated in interviews that he believes everyone should spend a minimum of six months in the military. He claims that the experience made him a better person and actor. "You're there to learn how to defend your country. You belong to the country," he said, "Then when you come out, you have a sense of belonging, rather than a sense of violence."
