I know you were making a particular point about BMI but really even the most cursory examination of many given statistics will reveal apparent glaring weaknesses in scope, definition etc etc
Very true, I have lost count of how many different "rankings" of universities, education, weight, etc I have seen cited on here. It is, however, quite interesting how, depending the source, the test group, etc, different charts measuring the same thing can be used in both sides of an argument.
On another note (i think it was Pete), you are right that the website is from North England (the website does say West Yorkshire). However obesity is a huge problem throughout the UK. I think, when you look at Poland (just not wanting to stray too far). Just a walk along the busy parts of town and on the trams, you will see a higher proportion of slim girls than if you did the same in the UK. This is limited mostly to young women though.
