As awareness（意识） of the benefits（好处） of humor increases, most of us want to get all the laughs we can. It seems that almost every day there is another new discovery about the power of humor to help us physically, mentally（精神上）, emotionally, and spiritually. Every system of the body responds to laughter in some important or positive way.
Many people mistakenly believe that we are born with a sense of humor. They think that when it comes to a sense of humor, “either you’ve got it or you don’t.” this is false. What is true, however, is that the ability to laugh and smile is actually something we are born with. For example, we laughed when we are tickled under the arm, even without thinking about how to react.
The parts of the brain and central nervous system that control laughing and smiling are mature（成熟）at birth in human infants（幼儿）, but that is not the same thing as having a sense of humor. (After all, when a baby laughs in a small bed, we don’t rush over and say, “That kid has a great sense of humor.”) Your sense of humor is something you can develop over a lifetime. Don’t be nervous before others and try to laugh at yourself – then you will make them laugh too.
Humor includes a lot more than laughing and joke telling. Many people worry needlessly that they do not have a good sense of humor because they are not good jokes tellers. More than jokes, a sense of humor requires being willing and able to see the funny side of life’s situations as they happen. In fact, one of the best definitions of a sense of humor is “the ability to see the non-serious element (元素) in a situation”.
There may be a thousand different ways to express your sense of humor, but joke telling is only one of those ways. As more discovered about how humor benefits our life, more people will be able to see and enjoy the humor when they are in a difficult situation. Life depends on air, food and water, but it is made easier to live with a good sense of humor.
