根据要求，回答问题：
A sense of humor helps us from several aspects. As awareness of the benefits of humor in- creases, most of us want to get all the laughs we can. It seems that almost every day there is an- other new discovery about the power of humor to help us physically, mentally, emotionally, and spiritually. 46 .
47 . 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 laugh when we are tickled under the arm, even without thinking about how to react.
A sense of humor can be developed in our life. The parts of the brain and central nervous sys-tem that control laughing and smiling are mature at birth in human infants, but that is not the
same thing as having a sense of humor. (After all, when a baby laughs in his small bed we don't rush over and say, "That kid has a great sense of humor." ) 48 . Don't be nervous before others
and try to laugh at yourself--then you will make them laugh too.
A sense of humor means more than telling jokes. Humor includes a lot more than laughing and joke telling. 49 . 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 hu-mor is "the ability to see the non-serious element in a situation".
A sense of humor helps people to better enjoy life. There may be a thousand different ways to express your sense of humor, but joke telling is only one of those ways. As more is 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. 50 .
