Here in Nova Scotia, a generation ago, every rural person who wasn't a
fisherman was (at least a part time) woodsman. [1] A commonplace
affliction was "whitefinger", viz. fingers that go numb and turn white
in the cold wayyy sooner that healthy fingers do.

They attributed it to the vibration from chain saws that were eagerly
adopted in the 50s.  Recent models have various sorts of vibration
dampers but before, say, the early 80s, no such thing.

Update: The project prep is done.  Next step is the Rube Goldberg
Memorial Grout Pump.  Stay tuned. :-)

[1] Okay, okay.  Woodsperson.  Many Old Timers recounted him on one
    end of the Swede saw and her on the other, junking [2] up the
    winter's firewood.  Family that saws together stays together. But
    not so many women actually worked in the woods.

[2] What a New Englander would call a bolt (of firewood) is here
    called a junk.
