Sea Legs are Illusions of self-motion (*).

"Neural adaptation or sensory adaptation is a change over time in
the responsiveness of the sensory system to a constant stimulus. It
is usually experienced as a change in the stimulus." (**)

After train rides I could still hear / feel the clacking of the
tracks for awhile. Same on long road trips where you might hear the
sounds of thumping when tires cross sections of the pavement.

I suppose log distance truck drivers get "road legs" and "road rash" on
their butts from sitting in the seat all day long? ^_^

TDD

Dunno. I thought long haul truckers got road roids.
