Why do we laugh? For years scientists have asked themselves this question. No animals laugh and smile—only human beings do. So does laughing help us to live longer? The answer seems to lie in that smiling and laughing help us to become less worried and calm, preventing illnesses that are caused by stress. Laughing is really the best medicine.
But if you’ re unhappy, it can’t do you any good to smile, can it? That’ s not true. It is clear that smiling works just in the same way whether you feel like smiling or not. Scientists in California asked a group of students to act five different feelings: happiness, sadness, anger, surprise and fear—just using their faces. Changes in the heart rate, blood pressure and temperature were recorded. Most of the feelings they acted didn’ t cause changes, but when the students smiled, their heart rate and their blood pressure went down. That happened even though they were only acting! So even if we feel sad inside, smiling seems to make us feel better.
Now, what makes us laugh? It seems that the answer to the question is far from simple. Everyone likes jokes, but we don’t laugh at the same ones. It depends largely on how old we are. There are some jokes, for example, that children love but older people might not find funny.
According to the author, ______.
