The way I remember Carl Sagan explaining this on Cosomos way back when, this is true only as long as you are still going at those different relative speeds. Once one of you applies acceleration in some direction to make up the speed difference, the "looks the same to each observer" aspect of relativity is off. Thus when you are done accelerating (decelerating) so that you and the other observer are at the same relative speed, you will indeed appear to have aged very little compared to them. That's the way I remember the explanation going, anway. (IANAP) --- T.E.D. homepage - http://www.telepath.com/dennison/Ted/TED.html home email - mailto:dennison@telepath.com
