Final answer:
Being 'on hold' on the phone when calling customer service is considered a 'daily hassle,' a form of stress that arises from our everyday experiences and irritations.
Step-by-step explanation:
When one experiences the frustration of being "on hold" with a customer service center, it is a form of stress known as a daily hassle. Daily hassles include minor irritations and annoyances that we encounter in our everyday lives, such as traffic jams, misplacing keys, or dealing with difficult coworkers. Research has suggested that the frequency of daily hassles can be a better predictor of both physical and psychological health than significant life changes. Furthermore, these daily nuisances can accumulate and cause a considerable amount of stress, impacting our overall well-being. Hence, among the options provided, being "on hold" when calling a customer service center is best categorized as a daily hassle, rather than a catastrophe, personal stressor, or significant life change.
