[sidebar] UK researchers conducted a statistical analysis of over 7,000 European individuals ages 50 to 70 to see the kind of impact retirement has on a person’s health. While most of us dream of days at the beach instead of the office, retirement, it turns out, isn’t such a good idea. (On the other hand, vacations are a different story.) Not when the study found it decreases the likelihood of “very good” or “excellent” self-reported health by 40%, increases risk for depression by 40% and diagnosis of a physical condition by 60%. While researchers note that health effects of retirement may vary based on the type of work a person does, the average effect among all workers is an issue, says the study. Based on these findings, researchers believe that there shouldn’t be a “normal” retirement age, and that workers coming up on retirement are an “untapped potential.” Something, it seems, Rivers has figured out.
