I understand why people always say things like this. It’s the not having a choice that ruins eternity. Fortunately it seems that such a fate is physically impossible in this reality. Even if you were made of the most durable possible material, you would still fundamentally be composed of baryonic matter, which means if you fell into a star, collided with a celestial object at relativistic speed, or fell into a black hole, you would surely die. There is always a way out for an enterprising immortal, and afterwards sweet nothing.
