Secrets of Body Language video response

I thought that the body language video shown in class was very imformative. This particular video shows us different types of body language and what those actions mean. For example by playing with your hands means that you are either bored or nervous. Another example would be for instance a teacher educating a very talkative class. He or she might be patient and cross their arms waiting for the class to be quiet or become upset and shout at them to be quiet.
