If you've got a big decision to make -- wait till your bladder is full.

That's the startling conclusion of a study performed by doctors in the Netherlands. In the study, subjects drank a lot of water then took a test as their bladders filled up. Doctors say people who had to go urgently made better decisions -- possibly because of an increase in brain activity as you concentrate on holding it in.

The study is published in the journal "Psychological Science."
