Individuals who are regularly stressed out by inconsiderate people around the are more likely to keep that stress with them. and pass it on to whoever is unfortunate enough to be near them.
People who experience such incivility keep the stress, negative emotion and perceived ostracism that results from those experiences, which then affects more than their daily lives – it also creates problems for their health and their well being.
A recent study surveyed hundreds of individuals and found that stress is like an out of control virus, it spreads around endlessly infecting just about everyone around them.
Of course we could just all start by being nicer to one another and not taking our problems out on others. Call me a dreamer, but perhaps we're on to something. ;-)
