It's entirely possible that some aging process makes a breaker more
sensitive, less sensitive, totally nonfunctional, etc. Such is the nature of
any design, man made or otherwise. Things change as they age. I just wanted
to make the comment that a deliberate electrical design to become more
sensitive as time passes is not even slightly, remotely possible for a
circuit breaker.

Now, if you wanted to argue that Detroit's engineers design shock absorbers
that are deliberately designed to age in such a way as to have less shock
absorption, then that is a whole different matter.........

That's what I think, too...

I can see there being an issue of a sizable _de_-sensitization w/ time if
there were some physical process going on in the bimetal or similar, but
I'd be quite certain if it ever was an issue it has been resolved long ere
now...
