As adults, we track a lot of numbers — from bank balances to credit card codes, shoe sizes to birthdays.

Now, how about your health numbers? Blood pressure, weight and cholesterol measurements offer valuable insight into the state of your body. The next time you’re at the doctor’s, jot down your numbers so you can start tracking your well-being. You’ll want to know your digits for these three measurements:

1. Blood Pressure. Normal blood pressure is considered to be under 120/80 mmHg.

2. Cholesterol. Ideal numbers are:

• Total cholesterol less than 200 milligrams per deciliter of blood (mg/dL).
• LDL (bad) cholesterol less than 100 mg/dL.
• HDL (good) cholesterol more than 40 mg/dL.
• Triglycerides (another form of fat in your blood) less than 150 mg/dL.

3. Weight. There are two ways to measure if you are at a healthy weight: BMI and waist measurement. A BMI of less than 25 is considered best. Waist size is important too, because too much body fat in the stomach area increases disease risk. A waist measurement of more than 35 inches in women and more than 40 inches in men is considered high.
