Some people sought laughter in extreme circumstances. More than 6 million Jews died in concentration camps. Viktor Frankl, who experienced the concentration camp, described the conditions of the camp in ``Night and Fog.'' In ``Night and Fog,'' Frankl also states that laughter does not destroy people's spirits. He proposes that we each make it our duty to find at least one funny story a day with his companion. He writes that laughter and humor helped him look at the concentration camp as a whole, including himself, with a critical eye. Frankl, who lived in a concentration camp, spoke of the deep connection between laughter and freedom.
There is also a trend of viewing laughter from the perspective of health. As you get older, your immune system weakens and you become more susceptible to infections. This deterioration of immune function is called "immunosenescence." As immunosenescence progresses, abnormal cells proliferate and become cancerous. However, cancer cells occur on a daily basis even in healthy people. If the immune system is normal, these cancer cells will be rendered harmless. However, as immunosenescence progresses, the immune system becomes unable to suppress the proliferation of abnormal cells. We now know that laughter and humor can improve the functioning of the cardiovascular and immune systems. It has become clear that laughter increases the activity of cytokines and natural killer cells, which have immune effects.
Comedy shows are a staple of television. This is generally a wholesome show. Television stations attract highly productive comedians who can get more laughs in a shorter amount of time. A situation arises in which the audience in front of the TV and the audience inside the TV laugh at exactly the same time at the performances of these outstanding entertainers. A good comedian can create an atmosphere of safety. People who are immersed in that atmosphere are more likely to laugh. When even one person laughs in that environment, a situation is created that laughter becomes contagious. Television stations have begun to find ways to take advantage of this phenomenon. The audience's laughter on TV has become a bit digitally manipulated. The digitally altered "laughter" is explained as a ratings issue. Even if you are not actively trying to laugh, there are situations in which you will laugh when prompted by a cue in front of the TV. As the exploration of laughter progresses, some people are finding business opportunities in it.
