Life Span vs. Age at Retirement
The pension funds in many large corporations (e.g., Boeing, Lockheed Martin, AT&T, Lucent Technologies, etc.) have been "Over Funded" because many "late retirees" who keep-on working into their old age and retire late after the age of 65 tend to die within two years after their retirements. In other words, many of these late retirees do not live long enough to collect all their fair shares of pension money such that they leave a lot of extra-unused money in the pension funds resulting in the over-funded pension funds. Dr. Ephrem (Siao Chung) Cheng provided the important results in the following Table 1 and the associated chart from an actuarial study of life span vs. age at retirement. The study was based on the number of pension checks sent to retirees of Boeing Aerospace.
Table 1 - Actuarial Study of life span vs. age at retirement.
Age at Retirement Average Age at death
Table 1 and the chart indicate that for people retired at the age of 50, their average life span is 86; whereas for people retired at the age of 65, their average life span is only 66.8. An important conclusion from nds. Dr. Ephrem (Siao Chung) Cheng provided the important results in the this study is that for every year one works beyond age 55, one loses 2 years of life span on average.
The 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.
The statistics shown in the Pre-Retirement Seminar in Telcordia(Bellcore) indicates that the average age that Telcordia (Bellcore) employees start retirement is 57. Therefore, people who retire at the age of 65 or older are minority as compared to the number of early retirees.
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.
These early retirees are not really idling after their early retirements to get old. They still continue doing some work. But they do the work on the part-time basis at a more leisure pace so that they do not get too stressed out. Furthermore, they have the luxury to pick and chose the types of part-time work of real interest to them so that they can enjoy and love doing that "fun" work at a more leisure pace.
The late retirees are small in number, tend to die quickly after retirement and disappear from the population of old people beyond the age of 70. Late retirees, therefore, have very little weight on the statistical average life expectancy of the population of "old people" dominated by the early retirees.
