It's time for the people of Somerset to get grinning- as today is National Smile Power Day.

The celebration- always on June 15- is a day for everyone to share the power of the smile.

Research has proven that smiling really does increase attractiveness and likability between humans.

Smiling at someone can also help them to relax and relieve stress.

See how many people you can bear a grin at today- and tweet us your smiley selfies @MercuryRebecca
