When the body's adrenaline is released in large quantities, muscles enter a state of high tension.
At this time, the body will tremble slightly, breathing becomes rapid, the head flushes with blood, the throat tickles, and concentration is highly focused.
Some people even experience enhanced vision, with their gaze becoming extremely focused, as the increased neural reactions create a "slowed down" perception of what they see.
This is the body's instinctive response to moments of danger and tension, a shot of adrenaline that ancient human ancestors experienced when confronting beasts and fights in the wild.
Of course, sometimes an excess of adrenaline can have a counterproductive effect, leading to excessive nervousness and causing people to act in bizarre ways.
For instance, when Kobe debuted on the NBA court, he ran to the wrong basket, almost making his first career shot an own goal.
