Instruction: Answer the question according to the text below:
Retire later to live longer
Early retirement, as is commonly believed, does not help retirees to live longer. This is the conclusion of a study published the British Medical Journal. The research involved more than 3,500 employees working in Texas over a 26-year period.
The workers retired at 55, 60 or 65 and were monitored to see what effect their age at retirement had on their lifespan. Researchers considered factors such as gender and socioeconomic status in discovering if retiring early is associated with better survival.
The results were astonishing. The life expectancy of employees who retired at 55 was significantly reduced compared with those who retired at the age of 65. The study concluded that retiring early at 55 or 60 was not associated with better survival than retiring at 65, and mortality was higher in employees who retired at 55 than in those who continued working.
The leader of the research, Shan Tsai said that although some workers retired at 55 because of failing health, these results clearly show that early retirement is not associated with increased survival. On the contrary, mortality improved with increasing age at retirement for people from both high and low socioeconomic groups.
