If we were to send a man into space at 99.99% of the speed of light. Would the time dilation allow him to live long enough to reach distant stars?

Time slows down the closer we get to the speed of light, so if somebody were to approach c, then wouldn't they in turn age slow enough to last a trip to say, Alpha Centauri?

EDIT: Thanks for all the awesome responses you gais. From what I'm understanding from the discussions is that the  faster the person on the rocket ship travels, he would experience time normally from his perspective, while observers on Earth would see him slow down. And if one were to actually travel at 1c, then the trip from his perspective would seem instantaneous.  Thanks again for your inputs!

That is correct. If a person is traveling at 0.9999c toward Alpha Centauri relative to Earth, then length contraction means they see the distance between Earth and Alpha Centauri as being about 0.062 light-years. Then they will experience only about 0.062 years, or around 22.5 days, before Alpha Centauri reaches them.
