Have you ever wondered about the origin of handshakes? You might be interested to know that the very nature of the handshake was originally intended to show oneself friendly.
    During the medieval times, when many of the men were covered in armor, the handshake was a manner of greeting used to show friendship.(18)If one male extended an open hand to another, this was understood to mean an extension of friendship and the gesture would be returned. Of course the alternative would be a hand extended with an accompanying dagger or sword. There is no doubt that the handshake was a way to determine whether one was a friend or foe.(19)The basic American handshake is very simple and most often used as a greeting between friends or new acquaintances.(20)Here’s how it is done: The right hand is extended, thumb up and palm flat. Grasp the other person’s hand using a firm grip, palm on palm. Hands are pumped two or three times in a vertical motion. The grip is released.
    You can definitely practice extending great handshakes with your friends and family members so that you can determine what is comfortable for you and others. Trying it out on a friend is much easier than starting it out with strangers.
