KNUCKLE WHITENING
●●●
The skin over the knuckles loses colour as the hand grips something — an armrest, a glass, the opposite hand — tightly.
MEANS
Intense stress, anger, or fear. The body is preparing for action.
CONTEXT
One of the most honest signals in the body. The hand grips before the face shows anything. Look for it on the armrests of chairs during difficult meetings or interviews. The grip almost always precedes verbal escalation.
NOT
A hand simply holding a heavy object.
