What's your BMI?
BMI stands for Basal Mass Index. It has to do with your weight, and as the weight goes up it becomes a risk factor, a component of the metabolic syndrome. Although you can make a gross estimate by the size of the shadow your body casts, there is a easy math to it. The constant is 704.5 multiplied with body body weight and twice divided with height in inches.
