It should be no surprise that a nutritious diet and regular exercise help us live longer. That's why these two must-haves appear in a top 10 list created by Dr. G. Medical Examiner.

Day in and day out, Dr. G. determines how recently departed people died. Sounds like a morbid job, doesn't it? It's actually pretty amazing if you watch her show, though. She takes clues from everything and sometimes comes to unexpected conclusions. For families that have lost loved ones without much warning, I expect that the explanation of their loved one's death helps to give them closure.

An expert in death, Dr. G. has come out with a book to help preserve life. Discovery Health has her top 10 ways not to die. Here are a few of her tips:

• Know your numbers. Keep your BMI in a healthy range by exercising and eating right. Check your blood pressure often. Have your cholesterol and blood sugar levels tested.
• Listen to your body. Don't ignore unusual pains or aches ... tell your doctor about any concerns you have.
• Use as instructed. Take medications according to your doctor's instructions.
