Due you mean in the Einstein "twin paradox" sense or are they actually aging significantly slower?

  According to Wikipedia astronauts that spent about 800 days in space have aged about 20 milliseconds less. But I'm not sure if that's the correct phrasing and usage of word "age".

    What about, "has experienced ..." or "passed through 20 ms fewer"?

    If you would consider someone who time traveled ten years into the future with magic to not be ten years older, then aged is correct.
