Relax
Too much stress, which is worry about problems in life, is not good for physical health. For example, it makes your blood pressure go up. Now we know mpre. Some stress is chronic, which means that it lasts a long time-for many months or years. Chronic stress can make people old. As people get older, they get gray hair and wrinkles in their skin, and their eyesight and hearing become worse. This is normal. But chronic stress makes people age-grow old-faster. A scientist at the University of California, San Francisco, studies stress. She can now identify how stress makes people age. It can damage (hurt) the body's DNA. The lesson from this is clear. We need to learn to relax.
