Space time and aging Would a more significant curvature of spacetime relative to earth (i.e. time on jupiter) effect the aging process? Basically would you age at a slower rate?
Or age faster on the moon?
Einstein's general theory of relativity explains time dilation. Wikipedia provides a concise summary:


  time dilation is a difference in the elapsed time measured by two
  observers, either due to a velocity difference relative to each other,
  or by being differently situated relative to a gravitational field. As
  a result of the nature of spacetime, a clock that is moving relative
  to an observer will be measured to tick slower than a clock that is at
  rest in the observer's own frame of reference. A clock that is under
  the influence of a stronger gravitational field than an observer's
  will also be measured to tick slower than the observer's own clock.


As one experiences more gravity, time seems to flow slower compared to (say) Earth. That means that "standing" on Jupiter, which isn't possible due to the gaseous surface, will cause you to move through time faster; but you do not age slower. Suppose your lifespan is 80 years. On Jupiter you still would live 80 years, but the time that has passed on Earth during your 80 years would be slightly more than that. 

The gravitational time dilation on the Moon is the opposite: the weaker gravity means that an Earth clock ticks very slightly slower than a Moon clock.
