When I was small and my grandmother died, I couldn't understand why I had no tears. But that night when my dad tried to cheer me up, my laugh turned into crying. So it came as no surprise to learn that researchers believe crying and laughing come from the same part of the brain. Just as laughing has many health advantages, scientists are discovering that so, too, does crying. Whatever it takes for us to reduce pressure is important to our emotional   health, and a study found that 85 percent of women and 73 percent of men report feeling better after crying. Besides, tears attract help from other people. Researchers agree that when we cry, people around us become kinder and friendly and they are more ready to provide support and comfort. Tears also enable us to understand our emotions better; sometimes we don't even know we' re very sad until we cry. We learn about our emotions through crying, and then we can deal with them. Just as crying can be healthy, not crying -- holding back tears of anger, pain or suffering -- can be bad for physical   health, Studies have shown that too much control of emotions can lead to high blood pressure, heart problems and some other illnesses. If you have a health problem, doctors will certainly not ask you to cry. But when you feel like crying, don't fight it. It's a natural -- and healthy -- emotional response  . Why didn't the author cry when her grandmother died?
Because her father did not want her to feel too sad. Because she did not love her grandmother. Because she was too shy to cry at that time. The author doesn't give the explanation.
