My major bone of contention is for active activities such as bush walking the majority of the participating population should be closer to the ideal BMI index so outdoor garments should be using a different ratio compared to the normal population.
Beware BMI as a measure. It is a blunt instrument. Recently they looked as a group of NRL players with less that 20% body fat. By BMI they were all obese, several morbidly obese. The body shape required in rugby league gives a high BMI. Percentage body fat, girth and recent studies of visceral fat have been better measures of obesity.
Now I have really have gone off topic!!
