Dr. Oz's Guide to Getting Healthy in Your 30s

Test This: Follow Your Heart

With the risk of developing heart disease increasing in your 40s, now's the time to undergo a basic cardiac exam. Your doctor will note any irregular heart or breath sounds, then test your blood pressure, pulse, "good" (HDL) and "bad" (LDL) cholesterol, and triglycerides; your current readings will serve as a baseline for future results. Keep your levels in check until you're 50, and chances are good you'll steer clear of heart disease for the rest of your life.
