Let's not forget that muscle tissue weighs a great deal more per cubic inch than fat does, and the BMI
doesn't take one's body fat percentage into account.
Just for comparison purposes I entered what I weighed in high school at my current height and received a score of "average", even though I was slat-thin almost to the point of looking emaciated then. Ironically, all the height/weight charts at that time listed me as grossly under
weight and suggested that I should weigh within ten pounds of what I weigh now.
