Drinking two pints of beer or two medium glasses of wine alcohol can sharpen the mind, say researchers.

A study by University of Illinois psychologists has found that men who enjoy a relaxing drink are actually better at solving brain teasers than those who are stone cold sober.

Not only did the thirstier chaps get more questions right, they were also quicker in delivering the correct responses, the Daily Mail reported.

It is thought that alcohol hinders analytical thinking, allowing creative thoughts that otherwise might be stifled to take root. This makes it easier to find imaginative solutions to problems.
