As JcbAzPx said, you’ll continue in all timelines where you’re alive. No matter of how injured you are. Eventually, you’ll be just a brain kept alive through thermal fluctuation. (Theoretically, entropy can spontaneously go down, the chances of this happening going down exponentially the more entropy we’re talking about. Think about shuffling a deck of cards, and getting a completely sorted deck of cards. Certain at 1 card, 25% chance at 2 cards, and basically zero at a full deck, but still theoretically possible.) Eventually, you’ll be a disembodied brain suffering for all eternity from phantom pain.
