We’re not consciously aware of doing it, but it’s a gesture that is duplicated by every culture on Earth. In fact, some experts claim it’s the most instantly recognised non-verbal sign of greeting used by humans.The trick is to watch for it when you meet someone you fancy. Better still, tell them you’re interested on a subconscious level by prolonging your eyebrow flash for up to one second - deliberately raise them while catching their eye for full impact.

Pointing. Sneak a peek at what their feet and hands are doing - we tend to point toward the person we’re interested in. If we find someone attractive, we’ll often point at them subconsciously with our hands arms, feet, legs, toes.

Again, it’s an unconscious indicator to make our intentions known. Unconsciously, this is often picked up by the other person, without them really knowing why.

So if you’ve got your eye on someone in the corner, point your body in their direction - even if you don’t make eye contact, they may take the hint.

Blinking. If someone likes what they see, their pupil size increases and so does their blink rate. If you want to up the odds in your favour, try increasing the blink rate of the person you’re talking to, by blinking more yourself. If the person likes you, they’ll unconsciously try to match your blink rate to keep in sync with you, which in turn, makes you both feel more attracted to each other!

Now, one final word before you go rushing off to the nearest bar to practise all this. Before you go, you must understand...

The golden rule of body language

Don’t judge on one thing alone. Sitting with your arms crossed is often perceived as a defensive, stand-off posture. But it might also mean you’re freezing cold, you’re having a fat day or just spilt coffee all over your top!

Don’t jump to conclusions, instead look for clusters of behaviour. If someone has their arms crossed and their lips are pursed disapprovingly, it’s a fairly safe bet they are on the defensive. Most body language experts favour the Rule of Four, which means look for at least four signals suggesting the same thing before totally believing it.
