At faster speeds, do you age slower?

kancha asked the Naked Scientists:
Hello there,

Great show and I enjoy the podcasts very much.

I have a question on mind about the slowing of time as one travels at faster speeds? Does the mechanical clock slow down if it is at a higher speed? And do the biological functions of the body also slow down giving one a longer life? Or is the slowing of time comprehended in some other way?

Thank you guys

What do you think?

Any clock will slow down at higher speeds relative to something stationary or of a lower speed. A person on a very fast moving spaceship will not live any longer than a person on earth, as far as each person can tell the same amount of time has passed. By earths clock, a person on the spaceship might launch from earth and not die for 200 years, but to the person on the spaceship it seems earths time is going faster, not theirs going slower.
