Anger is a inner inflammation as like kiln. This will make it to loose body soon.
Tension is a trembling of mustache, is a reddening of eyes, is a trembling of hands, legs, body.
These are all showed explicitly. Also loosens the lifetime.
So in anyway must not be angered. That should be demolished.
