Retirement is a one-way trip to insignificance.

Our reading
An editorial interpretation.
This is a bleak claim about leaving work. Retirement is pictured as a one-way trip with only one destination, insignificance, so stepping away from a career means fading from importance. It's a pessimistic aphorism, and it treats a person's worth as tied to their job.
