Early Retirement hits Mortality

Do early pensioners live longer?

Or, to rephrase this: What's the influence of early retirement on mortality?

The answer has been given in a 2005 BMJ paper called:

Age at retirement and long term survival of an industrial population: prospective cohort study

In a long term (1973-2004) cohort research, the mortality of past Shell Oil employees,who retired at ages 55, 60, and 65, have been studied.

Outcome
The main outcome of this study is that subjects who retired early at 55 and who were still alive at 65 had a significantly higher mortality than those who retired at 65 (hazard ratio 1.37, 95% confidence interval 1.09 to 1.73).

After adjustment, mortality was similar between those who retired at 60 and those who retired at 65 (1.06, 0.92 to 1.22).

So we may (carefully) conclude that working longer, means living longer...

Another interesting question, that hasn't been answered yet, is:
'what's the influence of early retirement on our healthy life years...
