Exposure to germs in childhood is thought to help strengthen the immune system and protect children from developing allergies and asthma, but the pathways by which this occurs have been unclear. Now, researchers have identified a mechanism in mice that may explain the role of exposure to microbes in the development of asthma and ulcerative colitis, a common form of inflammatory bowel disease.

I would say expose to some 'emotional germs' can strengthen our emotional immunity.
There is a correlation between antibody production and aging. Perhaps too many antigens stimulating the immune system makes people age more. Nature has a optimal number of antigens for normal aging. Some experiments with various types and amounts of antigens and correlating with lifespan would be exciting. Living longer with minimal allergies could result in a pleasant lifespan by develoment of a natural vaccine and immunization protocol.
