I may say, however, that in a sense there is a certain basis for this sentiment under certain circumstances. For crying, like laughter, has the physiological effect of producing a relaxation of tense nerves.
There is a fundamental basis for crying, but this applies only to exceptional instances in which there is too much nervous tension. When nerves are strained to the "breaking point," crying will bring about a state of relaxation, and one will feel better. If there are times of strain when laughter is utterly impossible, then crying might even be beneficial. The effect on the breathing is very much the same in both cases, and there is a curious similarity in the action of the diaphragm and the mechanical character of the expulsion of the breath. Looking tat a person from behind, one cannot tell whether he is laughing or crying. Both produce relaxation of the nerves, both increase the activity of the lungs, and both involve a form of gymnastics for the diaphragm and entire breathing apparatus.
But, while crying offers relief from extreme tension or grief, it does not justify crying for the so-called pleasure derived from it. Laughter is a pleasure, in itself, as well as a symptom of merriment. It is the expression of keen, bounding joy. It is an emotive manifestation that stirs one's whole nature and vitalizes every part of the body. There is a sound, physiological basis for amusements that make us laugh. Taking the world over, incalculable sums of money are spent for amusements that make us laugh, and it is money well spent. It is a sound and healthy instinct that leads the tired business man or the tired laborer to seek for mirth-provoking recreations. Professional "funny men" like John Bunny and Charles Chaplin undoubtedly add to the health of the human race, and they add to the vitality of those in whom they stimulate laughter. I feel sorry for anyone who has lost the power to laugh freely and heartily. When a man has brooded so much over the sorrows and miseries of life that he can no longer laugh, his condition is indeed serious.
"Laugh and the world laughs with you; weep and you weep alone," is one of the truest things that Ella Wheeler Wilcox ever said. For a laugh that is spontaneous and heartfelt is truly contagious, and in your little world, the circle of your friends, laughing brings a rich reward in increasing your own happiness as well as theirs.
The bodily expression and mechanical efforts that go with happiness will often induce the feelings and emotions associated therewith. To prove the accuracy of this statement, some morning when you are feeling especially gloomy and unpleasant, look into your mirror and go through the process of trying to make yourself smile. Screw up your features in such a manner as to force the required contractions of the facial muscles. If you continue your efforts long enough you will surely be rewarded by a real smile, and with the sense of good cheer that a smile will bring. You will make the surprising discovery at it is no longer an effort, for you will smile spontaneously.
To go even further try the laugh cure in the following manner. First of all assume a laughing position, in order to laugh properly and to secure the best results. Stand with feet far apart, and with the knees slightly bent. Now bring the palms of both hands down and "slap" them vigorously on the legs just above the knees, and then swing your bent arms overhead, making a noise as nearly as possible like laughing. Yes, you are quite right, it will sound very much like a cold stage laugh at first, and you will have to force it, but as you go on with the experiment it will gradually become more natural. Continue this long enough and I defy anyone to differentiate the emotions aroused from those associated with a real, spontaneous laugh.
In fact, if you have company while you are going through this process, I will guarantee that they will soon be "guffawing" loudly and violently. This experiment is an excellent one to thy on a company that is especially dull and in need of something unusual to awaken the spirit of good cheer.
