I’m the boss
Fear? Never heard of it! I am the top brass here and what I say goes! Placing your hands behind your head is one of the best-known dominance gestures. It is used almost exclusively by men— particularly by bosses and superiors during interviews or meetings. The raised arms show: I have no fear sweat. They are a symbol of self-assurance, strong leadership, and superiority.
If this gesture lasts no longer than 10 seconds, it may have a different meaning: It can also be a sign of well-being. If we obstruct our eyes, it can signify disbelief, doubt, or an attempt to avoid a situation.
