The table appears on a web page titled “Longevity Vs. Retirement Age” (or similar), which claims the data come from “pension checks sent to retirees of Boeing Aerospace.”

The same data shows up in a document referred to as Optimum Strategies for Creativity and Longevity (by someone named Sing Lin) referencing Cheng’s “study.”

However — and this is important — the “study” is widely regarded today as an urban myth, not a genuine peer-reviewed or publicly verifiable actuarial report.

The company itself (Boeing) reportedly issued a statement titled something like “Let’s Retire the Rumor about Life Expectancy,” saying there is no correlation between retirement age and life expectancy in its data.

Independent analyses (e.g. on forums and fact-checking blogs) note that no original study or data source — with date, method, sample size — has ever been published or verified.

In summary:

The chart you posted is a reproduction of that “Boeing / Cheng” table that’s circulated on the Internet.

There is no credible evidence that the underlying study was ever published in a scientific or actuarial journal.

The consensus is that the “study” is bogus, or at least unverifiable.
