How many of you take the sin of gluttony seriously? If people would get their BMIs in a healthy range, that along with some other healthy habits would go a long way towards cutting down costs of health care.
my doctor tells me:
a healthy (best longevity) BMI for women is 22-23,
and a healthy (best longevity) BMI for men is 24-25.

for people who train hard with weights, the BMI can be a little higher.
