Body language is a form of non-verbal communication, which consists of body posture, gestures, facial expressions, and eye movements. Humans send and interpret such signals almost entirely subconsciously.
Body language is the unspoken or non-verbal mode of communication that we use in every single aspect of our interaction with another person. It is like a mirror that tells us what the other person thinks and feels in response to our words or actions. 55% of the messages that we convey to other people are transmitted through body language. The actual verbal communication accounts for the other 38% in tone of voice and only 7% in the words we use (*When verbal context is ambiguous).
Body language may provide clues as to the attitude or state of mind of a person. For example, it may indicate aggression, attentiveness, boredom, relaxed state, pleasure, amusement, and intoxication, among many other cues.

Micro expressions were first discovered by Haggard and Isaacs over 40 years ago. They published a report on these expressions, which they called "micromomentary" expressions in 1966. The article they wrote was entitled Micro-momentary facial expressions as indicators of ego mechanisms in psychotherapy. Many subsequent studies have been conducted based on the research by Haggard and Isaacs, but the discovery of micro expressions should be attributed to them.
