Some people have no issues when it comes to flirting... others do spectacular faceplants just looking at their crushes. Fortunately, science does more than just send us to the Moon and help cure our diseases; science has also given us pointers on how to successfully flirt. From an evolutionary perspective, our biology is hardwired to find potential mates, and there are certain things we all find attractive on a fundamentally organic level.
So, while we can all agree that guy at the bar with the gold chains, shirt unbuttoned to the navel, and ridiculous pickup lines will probably have a hard time finding a bedmate for the night, there are some scientifically proven ways to flirt that even he could implement with relative ease. Though we may say otherwise, humans have a natural need for love and sex, and we can all benefit from knowing how to draw more of these things into our lives.
