When giving speeches, body communication is really important. If a sergeant is trying to build up the morale of his soldiers in a war, but the sergeant is shaking, then the men will know that the sergeant is afraid and their morale may drop even more. The body language of someone important should scream with pride and stature, this will quickly get people on their side and will help people listen more because of their body language makes them look important.
I love this example Pau. Having a strong body language improves the confidence that the audience has about the speaker.
Using body communication can definitely be used to imply different emotions, or roles like for example authority (seargent).
Love this example. It definitely is important to have strong management over your body and to have good self analyzation over your presentation.
This is a great example! Having good posture and body language during your speech can affect the audience just as much as your words.
