Quote:the BMI charts we had in the Navy umpteen hundred years ago were so far off no one was healthy 

BMI is a garbage estimate IMO. Underestimates fat on half of women, and overestimates fat on 25% of men. It has actuarial but not actual value. That may be good enough for insurance (and they love it for sure, easy way to increase rates by putting emphasis on BMI over other lifestyle like smoking, cholesterol, diet etc.). There is no doubt that an there is a coorelation between BMI and lifestyle diseases, but quite frankly its a lazy tool because body fat is rather hard to accurately measure unless you get the dunk tanks. Waist to hip etc, is at least better IMO.
