The whole "getting a physical" annually is purely an old school American thing anyway. I don't know anyone in my country who does this - although apparently nowadays US med associations recommended you go visit a doctor every 5 years or so if you're under 40.

Still, if I walked into a doctor and said "is anything wrong with me?" with no symptoms or obvious indication that this might be so, they would probably take blood pressure, do a breathing test, ask me if anything was actually wrong, and then wonder why I was wasting their time (or maybe ask if I was looking for a medical certificate cos I didn't feel like going to work, heh).
