Even if the days were shorter, the years would remain the same, just more days in a year.
God sets our lifespan, whether short or long.
Coriolis "force." Everything would slide off the table, you couldn't walk straight lines easily.
Rotation is not an inertial reference frame; it's one of constant centripetal acceleration.
Then again, we don't notice the rotational acceleration of the earth now--it's too mild. Come to think of it, 12 times as quick wouldn't likely be noticeable, either.
