If you move at speed of light then time seems to moves slowly..by equ. T'=T,/1-v^2/c^2 
.. and my friend..ur question is not completed..u dint said how much age the person has when he let earth..    
and you are talking about special theory of relativity (time dilation) ..



& the fact is that, noting cant move at speed of light, simple  in relativistic ideas, 
the equ. which i provided above that is time dilation equ. can solve out why u cant move in speed of light..  

Good to see a relativistic thinker here :) , and dude.. fill out ur quest plz.
