(I guess you will live shorter cause it is quite dangerous to > travel at this speed.) For the traveller aboard the ship, your time will appear normal to you, but will actually be passing slower than for those back on Earth. Of course, you need to appraoch pretty close to light speed to see this happen. Time dilation can be calculated by: [1-B^2]^0.5 The B is really beta which is the fraction of light speed you are travelling, so B=v/c As you can see, the effects don't become significant unless B is close to 1.
