My son in law is a licensed plumber, they say “The plumber protects the health of the nation”. It’s true.
After completing a five-year apprenticeship and passing the state test, he is required four hours of continuing education each year.
Not all this BS for a hair braider.
I have another relative that is a physician, at his graduation many years ago, they said, in the last century modern plumbing added 15 years to American lives, modern medicine add two years.

I would think that the sewer systems (no more out houses) and the modern materials for indoor piping systems, and water treatment systems connected to that were each and collectively bigger factors in that than the plumbers themselves. Once those big systems were figured out, designed, put in place and fell into common usage, learning the “plumbing trade” was a much smaller accomplishment.
