I'm 25 years old, and will be 26 in a few months. Should I start going for a yearly check up? I don't even have a regular doctor in Australia. They have these American-style massive centres full of doctors who give you around 5 minutes of their time and want to keep the conveyor belt moving. I could go find a single private practice doctor, but they're harder to get. Also, paying to go see a doctor? That's crazy in Canadian terms! Anyway, I might start going now, or I'll probably wait until I'm 30. Do you have an annual check-up? What sort of tests do they do on you at a check-up? I'm guessing they check your testicles for testicular cancer (if you're male or from Wales ), and check your heart rhythm. How does it feel, and what else do they check for?
