In an emergency situation, perhaps even in a state of shock, people are not able to think for long; their instincts kick in automatically! For example: a woman with a 10-year-old child is walking down the street, and suddenly a bus runs over her child's leg. A frail and weak woman might lift the bus with people in a state of shock, and she won't hesitate at the moment when her child is in danger; she won't waste time assessing the situation.
