Health Check Up - Suggestions.

I'm a 31 year old Male from Kochi, thought I'd do a health checkup. Don't have much of a health issue but just to check if everything is fine. What all should be the important tests that I need to take and things that I should look out for. And most importantly what all are the things that are unnecessary, Like unwanted tests which centers or hospitals push. Suggestions for doctors/centers/hospitals are welcome.
