BMI . . . Really?

Okay, so the National Institute of Health (NIH) institutes the Body Mass Index (BMI). According to wikipedia, BMI is defined as:

The body mass index (BMI), or Quetelet index, is a heuristic proxy for human body fat based on an individual's weight and height. BMI does not actually measure the percentage of body fat. It was invented between 1830 and 1850 by the Belgian polymath Adolphe Quetelet during the course of developing "social physics"

Guy Who came up with BMI 

Based on this information, this is a 160+ year old formula ((Weight in Pounds X 703)/ inches^2).
This will give you a number (1 - 50+) Based on this number, it tells you if your weight is average, above average, obese, worse than obese or under weight.

Rather than doing the math yourself, you can find calculator here:

Using Google, I searched the term, 'is bmi bs?' and had over 6.5 MILLION results. More or less, the BMI is outdated. One of the biggest downfalls of the BMI is that it does not take muscle mass into account. You can be 5'7 and 200 pounds of muscle and still be considered 'obese'. 

While I agree that I am overweight and maybe will even admit to being obese, BUT there is no way that I am on the end of the obese scale. My starting weight BMI is 34.6 and my goal weight (175) is still overweight with a BMI of 27.4.

I think that this should be changed or actual body fat should be calculated in this too.

Just my thoughts and a bit of a rant.
