But this is true in relativity as well. In an appropriate coordinate system, you are also moving in only 1 of the 4 dimensions. If you are not accelerating, then this coordinate system is an inertial reference frame, and the fact that you appear to be a stationary object moving through time is not mere mathematical curiosity, but the core insight of relativity.
