It is not always easy to make decisions about what is best for your health. The internet and media are full of information about health problems, diseases, research findings, and what we should and shouldn't eat, drink or do.
How do you know if the information is reliable or accurate? How do you know if your blood pressure is too high or too low, if your cholesterol is within a healthy range, or whether you should have a blood-sugar test, a cervical screening test or immunisation review? Knowing the numbers of key health measures can help you to know if you need to make some changes for the benefit of your current and future health.
