Here's a twist on this thought.
You could live to a very ripe old age if you go forward about oh, three decades, and check and see if you're dead yet. If so, you could find out the circumstances and prevent it, assuming it is something stoppable. Find out you have cancer, go back to a point and time and tell yourself about it so you can agressively avoid treat it. Get ran over by a little old lady from Pasadena, memorize the details and avoid it when it comes to time to.
See, there are even more headaches to have over this.
