Don't wait until you are really sick to go see your doctor. Get a check up. You never know what your blood work may come back with. You may have high blood pressure and not know it, or maybe your doctor will hear something in your lungs that should be checked out. Best to catch anything sooner then later.
Under most health insurance plans, regular checkups are free. You don't have to pay a co-pay and they don't count towards your health insurance deductible. There is no reason to not go.
