Well I get that question ALOT from my relatives, im sure many people do. What should I say? I say Physicist. They say wow very good, it's good to be in good physical shape. Working out is good. You know I walk 10 kilometres everyday. They must think Phys Ed is Physics Education or something. or they ask. "Well what does a physicist do?" I usually answer with something like, its the study which trys to understand the nature of matter and energy, otherwise known as the universe. Which they just ask the question a second time. They just don't know what physicists DO. What should I say so I can just get on with life without the generic questions?
