Is it ok to put activities or interests on a resume?

Is it alright to put activities or interests on a resume? Why or why not? I heard that it makes you stand out since most people don’t usually put their interests. What would be good things to write for interests or activities? In mine I put Interested in photojournalism, travel, and that is pretty much all I have. What else should or shouldn’t I put on there? What do you guys think? Yay or nay?
