This is a story told by a familiar doctor.
Before our era. An old man is coming. A sabloned tiger. Adrenaline is increased. He is ready to act. To escape, give the tiger an oak on the head. During physical activity, the level of adrenaline decreases.
2 of our days. A man goes to the office. A sabloned boss jumped on him. Adrenaline is increased. And lower it at all. Or give the boss a moustache or go smoke.
