Women less physically active

Studies show women are less physically active at both ends of the spectrum. This puts them at greater risk for osteoporosis, diabetes, and other diseases linked to low levels of physical activity.

The researchers, who focused on 10 and 11 year-old children in the school playground, found that boys and girls tend to play differently.

Girls tended to spend time in smaller groups and engage in verbal games, conversation and socialising.

Most boys, however, played in larger groups, which lend themselves more to physically active games, such as football.

Researcher Dr Nicky Ridgers said: "It is a concern that girls' activity levels are lower than boys and, although it is just one piece in a complex picture, this could be contributing to girls being overweight and obese.

"Schools should be aware of the differences between the way girls and boys behave in the playground and the fact that girls tend to favour small group activities.

So now if you see a fatty in the club, you can explain it away scientifically. Or, if you're Sinn, you can go pick her up.
