"The greatest deception men suffer is from their own opinions."

Well Mr Da Vinci, that may be the case, but I tell you, I'm right about this one thing... I have an almost genius ability to read people's faces.

Oh, I also know the answer to one your greatest mysteries, you irrepresible genius you.

Well, let me clarify about my genius ability; it's not bad for an ordinary joe anyway. I'm no Paul Ekman - he's a bloke who has written a whole bloody manual on reading faces, (FACS), cataloguing every single type of expression a face can make. Apparently, these facial expressions, i.e. disgust, fear, hatred, contempt etc are universal.

The interesting thing about this malarky is, you can't hide these expressions. They may only appear fleetingly, but nevertheless, if someone asks you a question and you intend to lie, for a fraction of a second, your face will give the game away.

That's what the TV series, Lie To Me is about. You have this independent company headed by Tim Roth who specialise in finding out if people are lying by either using FACS or body language.

In the pilot, a character called Ria Torres is poached from her job as she is a 'natural' at reading faces, body language etc and ends up with a briefcase full of money as a 'signing-on' fee!

I want that, I'm a natural! Anyone know a real life company that does this? If they want a CV, just tell them that I got 100% in the following test;

FAKE SMILE TEST

As for Leonardo, probably the greatest genius that ever lived, inventor of SCUBA gear, the hanglider, the helicopter, mirrored writing adept etc etc, you'll always be known for one thing - Yep, the Mona Lisa.

By the way, the answer to Da Vinci's most famous enigma about Mona Lisa's smile? Yeah she's faking it!
