I maintain a constant weight of 320 grams (11.3 ounces) with no effort.

There’s a lot of discussion these days about people being overweight and the related health risks. So I decided to check my Body Mass Index (BMI).

You take your weight in kilograms and divide it by the square of your height in metres. Just the job for my red calculator. The answer was 3.1.

According to the experts, anything below 18 counts as underweight for a human. Being a teddy bear, I’m not worried.
