Are You Good At Reading People? Here's How To Spot A Fake Smile

How could a smile be so deceiving? Well apparently it can, according to this new video from In59Seconds.

The video, which shows how to sniff out a fake smile tests your ability to spot a facial expression that isn't so real - and we don't mean to brag, but we got full marks on the test.

So, if you're feeling like your Sherlock skills are on form then watch the video, spot the signs of a fake smiler and let us know how you did!
