Ignoring medical tests
No question, good genes help with healthy aging. But you still have some control here. Make sure you ask your doc when and how often to have these screenings: blood pressure, colonoscopy, PSA (prostate), mammogram, pelvic exam and pap smear, eye exam (macular degeneration, cataracts and glaucoma are common with age), cholesterol, vaccines (shingles, pneumococcal, flu shot, tetanus), and bone density. Of course, also ask about the frequency of tests for any specific ailments you suffer.
