"She lives as a man in her body."
Translation:Sie lebt als ein Mann in ihrem Körper.
Good question! "as" and "like" can be considered as synonyms, but in this example the difference in meaning is significant enough. "She lives AS a man in her body" - She feels like a/identifies as a man. "She lives LIKE a man in her body" - She may still feel like a female, but acts in the body like a man would.
