The lives of rich people seem to be getting better and better. Rich people generally have better homes than poor people. They usually have better jobs and better schools for their children, too. Now, a new study finds that the rich may even have better stress than poor people. Stress is the way the brain reacts to any kind of demand or threat. The American Psychological Association says it is part of our body’s fight-or-flight response. When faced with danger, stress can create energy to fight off an attacker. It makes the body release hormones that increase our heart rate and blood pressure. That is the stress of ancient times. In modern times, stress can help you give a great presentation at work or win a sporting event. This is short-term stress that leads to success in accomplishing a goal. This is a good kind of stress. And it is the stress that most rich people have. But many problems with life or work can cause stress. Stressors are the bills that you can’t pay; the childcare that falls through at the last minute; or the car that won’t start. These stressors add to what experts call chronic stress.
