You cannot naturally choose to change your frame of reference regarding time at all. You are in my frame of reference regarding how fast time will pass. You can however naturally "travel" very, very long distances on foot. And if you are going to use, "relative" distance when regarding spatial distance, then you should regard the amount of variance you are naturally able to create in the passage of time between you and another person relative to, say, a millenium. That is only fair. I was just basically saying that if we wish to speak metaphorically, about travelling through time instead of being pulled along by it, controlling life, taking it by the horns, etc. or whatever, there isn't any good argument against that. P.S. regarding charity - if i just said, "well, yes, we DO all travel through time", there wouldn't be much to discuss here.
