Thread: time dilation

Do we age slower on Earth than if in space or outside the galaxy?

Our solar system rotates around the center of the Milky Way at about 900000 km/hr. The Earth moves around the Sun at around 107,300 km/h. The Earth also rotates on its axis at approximately 1670 km/hr (at the equator).

So does that mean if we were out of orbit of earth, outside the solar system, or outside of our galaxy we would age quite a bit faster? Though I don't see how it would matter since we would do everything faster, correct?
