I believe that the ability to interpret body language remains as long as people are physically born and exist. You're generally very good at reading someone. Only if you would be asked what the person feels most likely to feel at the moment, uncertainty can appear, because the person in question wants to judge correctly in the end. He wants to achieve a good result in front of the questioner, maybe even be praised. Another stumbling block is to ignore what you have just experienced through body language and instead question your mind. The mind is like a huge supermarket shelf: it starts to offer all kinds of varieties and tricks itself by giving in to a wish instead of the expressed posture. There is the wish the father of the thought that someone has bad intentions towards you or someone else when he makes a serious face. But let's not fool ourselves, even behind a smiling face we can recognize anger, sadness or fear if we remain open to it.
in my opinion people have been using the unspoken kind of communication rather wrongly, sometimes the things we cannot say we usually communicate through our gesture and body language, but after looking at so many cases I often wonder, do we really need to be educated on the use of gestures and body language in order to utilise it to a powerful method of communication?
I click my tongue :)
This is a very good observation. Yes, people always communicate something they don't dare to say. They can't even suppress what they don't want to say out loud. Whether it requires education to use powerful physical communication? Well, not necessarily by others, but rather by a self-enlightening interest in the subject.
