Deborah Ford really takes that whole “neither rain nor hail” mantra seriously.

The Detroit woman retired last week after 44 years with the United States Postal Service and never taking a sick day during her entire time on the job.

For her efforts, Ford was honored with a luncheon in her honor where co-workers and superiors gushed over her tenure. Chuck Howe, who oversees postal service employees in Detroit, gave her a proclamation “enabling you to retire with a sick-leave balance of 4,508 hours.”

As for how Ford managed never to take a sick day, she succinctly said, “I wasn’t sick.” And her secret? “I have no secrets. But a positive attitude helps.”

That’s a pretty impressive immune system she’s sporting, especially in this brutal flu season.
