Why company of good like-minded is must for our existence?
Why do we require control over what type of entertainment we are exposed to?
Why is it necessary that our recreation activity happen in like-minded group?

Human beings continuously emit chemicals into the air by breath and through the skin. These chemicals are imbibed by co-humans sharing the environment. Spending time together syncs our mind and body. Those in majority, can influence rest. Your mood and mental state emits unique chemicals.

It is now possible to determine whether a movie scene is full of suspense, funny or somewhat boring, using chemistry.

“Interestingly, the two film scene labels with the most significant linkage to chemicals measured were “suspense” and “comedy”. These could be interpreted as an evolutionarily advantageous alert/stand-down signal, if perceivable by others34. Humans possess a very well developed sense of smell35, and new evidence suggests that recall is more effective36, and our perception of faces changes with odours present37. Therefore the chemical accompaniment generated by the audience has the potential to alter the viewer’s perception of a film.

There are several important consequences of our finding that human beings respond to audiovisual cues through breath emissions. Firstly, in the field of medicinal breath analysis, where chemical markers for diseases such as cancer are being sought2, emotionally induced emissions have the potential to confound disease marker identification. The strong response found here for “suspense” suggests that a patient’s state of anxiety should be taken into account in future medicinal breath studies. These findings also have obvious industrial applications where an objective assessment of audiovisual material is sought from groups of people, for example, in advertising, video game design or in film making.”



Cinema audiences reproducibly vary the chemical composition of air during films, by broadcasting scene specific emissions on breath

Human beings continuously emit chemicals into the air by breath and through the skin. In order to determine whether these emissions vary predictably in response to audiovisual stimuli, we have continuously monitored carbon dioxide and over one hundred volatile organic compounds in a cinema. It was found that many airborne chemicals in cinema air varied distinctively and reproducibly with time for a particular film, even in different screenings to different audiences. Application of scene labels and advanced data mining methods revealed that specific film events, namely “suspense” or “comedy” caused audiences to change their emission of specific chemicals. These event-type synchronous, broadcasted human chemosignals open the possibility for objective and non-invasive assessment of a human group response to stimuli by continuous measurement of chemicals in air. Such methods can be applied to research fields such as psychology and biology, and be valuable to industries such as film making and advertising.
