Many people are stuck working at a job that they hate for various reasons. Hannah Nichols's article on medicalnewstoday.com explains how working at a job that you are unhappy with can actually have negative effects on your health by the time you reach age 40. The article talks about a study that collected information about how satisfied people were with their jobs. The people they collected data from were between 14-22 years old at the time. They continued the research until the participants reached age 40, and had found various health issues that participants who were constantly unsatisfied with their job had in common.
