i assume the ceiling fan is in the center of the room, so in the winter
it blows air down in the center, and the air rises up along the inside
of the exterior walls and back along the ceiling, where the fan blows
it down again, in a rotating toroidal pattern...

because the walls are cooler than the room... agreed?

hmmm.

you might drill a hole for a 4" eyescrew and see if you can hang from it,
starting with little tugs. ceiling fans only weigh 20 pounds or so, and
they don't usually vibrate enough to disturb a joist.
i hung all kinds of furniture from the ceiling of one city apartment,
including some huge wooden cable reels suspended by single ropes which
i used for rotating bookcases. for the homemade swinging couches i went
up to the attic and drilled holes down through the joists and used big
eyebolts with nuts and washers on the topside, vs the eyescrews that
didn't fully penetrate the joists.
