"The body mass index has long been criticized as a flawed indicator of health. A replacement has been gaining support: the body roundness index." Article unfortunately doesn't give the freaking formula for chrissakes; it's "364.2 − 365.5 × √(1 − [waist circumference in centimeters / 2π]2 / [0.5 × height in centimeters]2), according to the formula developed by Thomas et al.10"
As a separate person, Drag is not Dragonfucker but concurs that Drag pronouns make Drag sound very cool, and Drag would like to adopt Drag's neopronouns for Dragself as well.
It "works" for me, but if you want to put in xxx in CM, it might not be there because they stick to inches and you need to round up/down :/ For example, it goes 170cm to 173cm
But I do have extra dense bones apparently, which tends to be mostly what screws with my BMI, and my ability to float/swim. But they seem really hard to break, not that I try very hard... but none of them have broken yet. And I've been in situations that seem like they should have broken.
Either way, I weigh alot more than I look like I should, not quite "Wolverine getting on a motorbike", but a bit like that.
Kinda makes me wish those "guess your weight" carnival experts were something I could see in real life, only ever seen it on TV.
I think interestingly enough it's inaccurate in the other direction. While BMI is will call people unhealthy if they have a lot of muscles, this will call people healthy if they are like me severely underweight.
My roundness index claims it's in the healthy zone while in reality my weight is unhealthy.
I'm currently receiving treatment for onset osteoporosis caused by malnutrition. Also it's kinda obvious your weight is probably not healthy when your ribs are sticking out.
