its all relative!
you people saying 1 minute is 1 minute arent thinking of relativity
what your saying only applies for "earth" time, and not about speed!
the fact is
if 1 person spends his life sitting down
and the other person spends all his life sprinting
when both of them die, the watch of the person who was sprinting all his life could be a few seconds earlier
and about that 8 minute- 7 minute thing
if you save 1 minute on a specific distance, that means that you were going @ (lets say) 10km/hour more
that is NOTHING compared to the speed of light so you wont even see a difference!
but theoretically, you went a few billiseconds into the future
