The study, published in the British Medical Journal, involved more than 3,500 employees working for Shell Oil in Texas. The workers retired at 55, 60 or 65 and were monitored for up to 26 years to see what effect their age at retirement had on their life-span. Factors such as gender and socioeconomic status were taken into account.
They found that workers who retired at the age of 55 had a significantly higher mortality compared with those who worked until 65.
In fact, the death rate was almost twice as high in the first ten years after retirement at 55 compared with those who continued to work. [Scotsman, Oct 21 2005]
All work and no play is bad, but all play and no work is much worse.
