Jerky

The nervous system is spread throughout your entire body and affects the internal balance.
Many people are jerky and twitchy; like a nervous bird looking for food.
They do not move in a relaxed, fluid manner.

Being restless and agitated affects body language, and can make the individual emotionally volatile.
These people appear to be profoundly uncomfortable in their own body: irritable, tense, bored, fidgety.
