Body language, talking without saying something becomes: saying something without talking.

The language of the body is universal.

The way you walk, the way you talk, the expressions on your face and many other signs tell a lot about you and your health. As a teener already I loved to sit near the Central Station in Rotterdam and watch all those peeps go by. At the age of 19  I learned how to read this language. Or should I say: some of the languages, 'cos there are differences between them. The oldest  is 'baby talk', a language every mother knows how to understand. It isn't verbal yet but it is communication. Signals from the hands, gesticulation and moves are another language ( I mean the body language, different from the deaf  or mute language ). Eyes, mirrors of the soul tell a lot....A mouth can talk without saying something..You know what I mean..?
There's a difference in how younger people show what's going on and how the elderly do. Like how and why a 20 year old limps and how and why a 70 year old does so...!! The younger one most likely pulled a muscle  during a sprint while the older person might have arthritis or a war injury...that's another language....!
All my life I've had animals around me, they not only speak their own language but do dialects as well...( I have a highly respect for vets).

 As a therapist it comes in handy when you can tell what's wrong just by observing. Yeah, brown finger tops tell me you smoke, so does a cracky low throat voice. A big nose and open pores tell something about alcohol habits, the color of the skin says a lot about your health.  Red eyes?? You probably smoked a joint..!!  Some info however is camouflaged and give false signals. The natural body smell, (sweat, breath and hormones) are washed away, shampoo's, aftershaves, toothpastes and deodorants spread a confusing aroma instead and mask any illness or malfunction that comes with the scent. Ever noticed what animals do when they meet...?? They use their nose..............!!! And they go for the butt first....There must be a lot of info coming from that place.

Actors can fool you, without saying a word.....it's not for real but you believe them...!

I think many 'emoticons' or so called smiles were invented by Charly Chaplin.

  He could tell a story without soundtrack. That's an art. 

Nothing new so far. Now what if I tell you that each emotion has its own adrenaline like endorfine, I'm sure they all have a name, (Google for that), but each expression (often even when faked/acted)  releases a hormone that fits the category. That's why a good actor can cry real tears....so more or less  controllable factors.
There's more than expressions and poses, the physical structure of the whole body, especially the head, reveal more than you might think. The form of the scull, the shape of the chin, the size and shape of the ears.......

That's why casting buro's introduced character- and type casting.
