1. I know my waist circumference.
Men whose middles are more than 40 inches around or nonpregnant women whose waists exceed 35 inches are at higher risk for obesity-related conditions, including heart disease, diabetes, and stroke.
2. I know the three types of exercise I need.
Aerobic exercise (walking, biking) improves heart and lung fitness. Strength training (weightlifting, weight-bearing exercise like jumping jacks) promotes bone strength. Flexibility exercises (tai chi, yoga) improve the range of motion in joints, which is especially helpful if you have osteoarthritis.
3. I know my family health history.
Having your family health history—including ethnicity, chronic diseases, causes of death—helps your doctor recommend actions for reducing your risk of getting a disease that runs in your family. So collect health data from the whole clan—it might change the course of your personal health history.
4. I know my blood pressure numbers.
Blood pressure that's at or below 120/80 mm Hg is normal. High blood pressure is when that first number is above 140 mm Hg or the second is above 90 mm Hg. High blood pressure (aka hypertension) has no symptoms and can become life-threatening. Have yours checked at every doctor visit.
5. I know why I need to sleep 7 to 9 hours every night.
Insufficient sleep has been linked to numerous risks, from developing diabetes and heart problems to having a car accident. Since hormones that control appetite are regulated during sleep, lack of shut-eye might also lead to greater hunger—which could mean weight gain and a higher BMI.
6. I know the symptoms of diabetes.
Untreated diabetes can be fatal. So get checked if you have one or more of these symptoms: frequent urination; unusual thirst, hunger or weight loss; extreme tiredness or irritability; slow-healing cuts; recurring bladder, gum or skin infections; blurred vision; tingling or numb extremities.
7. I know what BMI means—and what mine is.
Body Mass Index (BMI) is an indicator of body fat and can tell you whether you're at a healthy weight. Carrying excessive weight may contribute to health problems such as high blood pressure or high cholesterol.

Use this formula to calculate your BMI:
BMI = [ weight in pounds ÷ (height in inches)2 ] x 703.

Here's what your final figure means:
Less than 18.5 = underweight
18.5 to 24.9 = healthy weight
25.0 to 29.9 = overweight
30.0 or higher = obese
8. I know when to get a colonoscopy.
Colonoscopies can detect colorectal cancer early, when it's easier to treat. Most people should have their first colonoscopy at age 50. If there's colorectal cancer in your family, you have an inflammatory bowel disease or you are African American, earlier screening might be necessary.
9. I know my cholesterol numbers.
In general, healthy cholesterol levels—those that mean a lower risk for heart disease and stroke—are:
• Total cholesterol: less than 200 mg/dL
• LDL ("bad" cholesterol): less than 100 mg/dL
• HDL ("good" cholesterol): 40 mg/dL or higher.
• Triglycerides: less than 150 mg/dL.
10. I know how much fiber I need.
Dietary fiber can lower blood sugar and cholesterol levels, make you feel fuller on fewer calories and protect against cardiovascular disease. Women need 25 grams each day, while men need 38. Get it from a diet rich in whole grains, legumes, fruits and vegetables.
11. I know when—and how often—to have a mammogram.
Mammograms are the best screening tool for identifying breast cancer early, when it can be treated. Women should begin annual mammograms at age 40 and continue for as long as they remain in good health.
12. I know when to take a skin spot to the dermatologist.
See a dermatologist about any moles that are asymmetrical, have irregular edges, contain different colors, change shape or color over time, or are larger in diameter than the end of a pencil eraser. If caught early, more than 95 percent of skin cancers are curable.
