This is the analysisOptimum Strategies for Creativity and Longevity By Sing Lin, Ph.D
This is the conclusionThe Boeing experience is that employees retiring at age of 65 receive pension checks for only 18 months, on average, prior to death. Similarly, the Lockheed experience is that employees retiring at age of 65 receive pension checks for only 17 months, on average, prior to death. Dr. David T. Chai indicated that the Bell Labs experience is similar to those of Boeing and Lockheed based on the casual observation from the Newsletters of Bell Lab retirees. A retiree from Ford Motor told Dr. Paul Tien-Lin Ho that the experience from Ford Motor is also similar to those in Boeing and Lockheed.
I get the feeling there is a flaw in the analysis, but because there is no data, it’s hard to say exactly what it is.The hard-working late retirees probably put too much stress on their aging body-and-mind such that they are so stressed out to develop various serious health problems that forced them to quit and retire. With such long-term stress-induced serious health problems, they die within two years after they quit and retire.
On the other hand, people who take early retirements at the age of 55 tend to live long and well into their 80s and beyond. These earlier retirees probably are either wealthier or more able to plan and manage their various aspects of their life, health and career well such that they can afford to retire early and comfortably.
Good link. ThanksThis analysis has been discussed many times on the forum - search the forum for "Boeing" and you'll get lots of hits. Here's a thread from 2004 dissecting the many flaws in the analysis:
