If we don’t use up these chemicals, or if we produce too many of them, they may actually harm us, usually this kind of feeling we call it stress. The parts of the body that are most affected by stress are the stomach, heart, skin, head and back. Stress can cause car accidents, heart attacks, and alcoholism, and may even drive people to suicide.
    Our living and working conditions may put us under stress. Overcrowding in large cities, traffic jams, competition for jobs, uncertainty about the future, any big change in our lives, may be stressful.

Also if you have changed jobs or moved house in recent months you are more likely to fall ill than if you haven’t. In addition more people commit suicide in times of inflation.
    As with all illnesses prevention is better than cure. A very common danger signal is the inability to relax. When you’re taking work home, when you can’t enjoy an evening with friends, when you haven’t time for outdoor exercise that is the time to stop and ask yourself whether your present life really suits you.
