Originally a public domain film from the Library of Congress Prelinger Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied.
The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original).
Individual animals regularly clean themselves and put their fur, feathers or other skin coverings in good order. This activity is known as personal grooming, a form of hygiene. Extracting foreign objects such as insects, leaves, dirt, twigs and parasites, are all forms of grooming. Among animals, birds spend considerable time preening their feathers…
Grooming as a social activity
Many social animals adapt preening and grooming behaviors for other social purposes such as bonding and social structure enforcement. Grooming plays a particularly important role in forming social bonds in many primate species, such as chacma baboons and wedge-capped capuchins.
Mutual Grooming in Human Relationships
In human kind, mutual grooming is quite related to social grooming, which is defined as the process by which human beings fulfill one of their basic instincts, such as socializing, cooperating and learning from each other. Research conducted by Holly Nelson (from the University of New Hampshire) and Glenn Geher (State University of New York at Platz), individuals who chose their romantic partner reported more mutual grooming than others who focused in other types of relationships. Hence, this study hypothesized that mutual grooming was related to relationship satisfaction, trust and previous experience of affection within the family. They claim that even though humans do not groom each other with the same fervor that other species do, they are groomers par excellence. Therefore, human mutual grooming plays an important role in pair bonding. In the same investigation, researchers found that individuals with more promiscuous attitudes and those who scored high on the anxiety sub-scale on an adult attachment style measure, tend to groom their partners more frequently. These findings were also consistent with some of the functions of grooming: potential parental indicator, developing trust and courtship or flirtation…
In emphasizing an ongoing procedure or set of habits for the purpose of maintenance and prevention, the concept of cleanliness differs from purity[disambiguation needed], which is a physical, moral, or ritual state of freedom from pollutants. Whereas purity is usually a quality of an individual or substance, cleanliness has a social dimension, or implies a system of interactions. “Cleanliness,” observed Jacob Burckhardt, “is indispensable to our modern notion of social perfection.” A household or workplace may be said to exhibit cleanliness, but not ordinarily purity; cleanliness also would be a characteristic of the people who maintain cleanness or prevent dirtying.
On a practical level, cleanliness is thus related to hygiene and disease prevention. Washing is one way of achieving physical cleanliness, usually with water and often some kind of soap or detergent. Procedures of cleanliness are of utmost importance in many forms of manufacturing.
As an assertion of moral superiority or respectability, cleanliness has played a role in establishing cultural values in relation to social class, humanitarianism, and cultural imperialism…
