And if you are clued up, you can even learn to decipher essential body clues to learn more about a person's feelings. But learning to read basic body signs is relatively easy.

Eye contact is the most common initiation of interest by a member of the opposite sex.
The eyes reveal myriad emotions - interest, excitement, anger and even disinterest.
