The ' many worlds ' hypothesis of quantum mechanics is correct and ' quantum immortality ' obtains.
If that's the case, you will live, no matter how unlikely that is, esstenially forever. You're going to live unitl ' machine transcendence ' is achieved and you are ' uploaded ' into a computer and become essentially immortal ( or whatever form it may take, The Second Coming happens, The Singularity, The Omega point, etc )
I may die in your world and you may die in mine, but you will live forever in yours. But it's possible that after this transcendence that You will not be the same You that You are Yous to.
