It's Not Magic, It's Work!

If you ever want a quick, simple and modular wiki, then Brian's Kwiki is worth looking at. It's dead easy to install, and while not as feature complete as others, it offers a good selection of features to cover most needs.

I like it so much that I've contributed to the xhtml.

The Body Mass Index

Today I had my weight measured. I'm still over weight, but it has come down 4Kg since last year, so things are moving in the right direction. My target was 85Kg, which given that I have a heavy broad frame sounds like a fair target.

For fun I calculated my BMI, it's too high. I then re-calculated with my target weight, it's still too high. According to the US CDC I should weigh between 53-72Kg. If I did weight 53Kg then I would look very thing and sick. If I got down to 72Kg then would still look pretty thin, and unwell, but not emaciated.

I know it's a simple formula BMI = weight (kg) / square of height (m), but if you ask me, volume is a cube relationship with length, not square. So BMI values can't be very meaningful if you are tall or short. Didn't the medics who came up with this do any maths at school?
