Re: Why retire young?
Ephrem Cheng (aka sing lin...doesnt the fact that the originator uses aliases make you all warm and fuzzy about the study?) built this analysis on the basis of data he got second hand from Boeings actuarial department, and it was "supported" by anecdotal information from other people.
It is initially suspicious because of the linearity of the data itself.
On further review and when Ephrem was challenged, he recontacted his actuarial friends at Boeing who acknowledged that the data had been "floating around" for more than 20 years and nobody knew where it had actually originated.
A current study done at Sandia labs in 2001 indicated that regardless of the retiree date, age at death spanned a 30 year period. The correlation between retirement age and longevity was only .37, extremely low.
On recontacting Boeing with this new Sandia data, Boeing acknowledged that the new data was consistent with current data they were using.
The determination from this is that the original Boeing data was a hoax or simply a bad conclusion drawn from bad, aged or mixed data.
Do a search for "boeing" and you'll get my total, 3 full length post analysis of this study.
Be fearful when others are greedy, and greedy when others are fearful. Just another form of "buy low, sell high" for those who have trouble with things. This rule is not universal. Do not buy a 1973 Pinto because everyone else is afraid of it.
