OK, so I am pretty bored. All this talk of food and tabs' fine 6'5" 320lb physique, and my own newly discovered cycling regime, plus innumerable articles in the local paper about the increasing "size" of the world, have made me want to create a poll. (edit) By the way, I'm not looking to rag on anyone here - I'm just curious.
This poll will measure Pelicanites' BMIs - body mass index - the slightly spurious measure of overweightness and obesity used by the media etc.
BMI is calculated two ways:
- (weight in kg) divided by (height in metres squared)
In my case, 75/(1.84*1.85) = 22.
OR:
- (weight in pounds times 703) divided by (height in inches squared)
In my case, (165*703)/(72.8*72.8) = 22.
tabs will be (320*703)/(77*77) = 38.
What does BMI mean? When you see "50% of Americans are overweight" in the media, it means "50% of Americans have a BMI of over 25". Obese is defined as a BMI of 30 or greater. Over around 40 is "morbidly obese" - ie likely to kill ya.
BMI of less than 18.5 (for adults) is referred to as "underweight".
It is a spurious measure because it measures the following poorly:
- muscley (sp?) people (for instance, Governer Arnie is probably "overweight")
- Pacific Island people (larger, heavier bone structure, greater muscle mass). I'm sure this applies to other ethnicities too
- doesn't really apply to children (tell that to the NZ media)
I thought I better check my maths and stuff, and lo and behold, an online calculator and people who know far more than I:

So anyway, take part in the poll and make me happy
. I will be surprised if 20 people bother
