Obesity harms 'later brain skill'

Another study showing that fat people are stupid.

Being overweight in later life puts you at higher risk of brain decline, Korean research suggests.

A study of 250 people aged between 60 and 70 found those with a high body mass index (BMI) and big waists scored more poorly in cognitive tests.

The Alzheimer's Society said the research, in the journal Age and Ageing, added to evidence that excess body fat can affect brain function.

And brain function is not affected for the positive.
