It&#x27;s interesting that Quetelet Index aka BMI is arguably &#x27;wrong&#x27; as it&#x27;s comparing volume of something with one dimension ^2 instead of one dimension ^3.  There are reasons it&#x27;s valuable in human health as square cube law scaling has negative consequences.  Still, it&#x27;s interesting just how &#x27;old&#x27; that measurement is.
