Fire is a natural and necessary part of many ecosystemsm. It keeps parasitic insect populations down, stuff like ticks and chiggers, and some plant species rely on fire to prepare the soil for seeds and even is required for some plants to release their seeds. In dry ecosystems like the western USA it also consumes old dead plant material, reducing the fuel available for future fires and reducing fire severity overall. Many foresters and fire fighters advocate for increasing prescribed burns, essentially forest fires that we light on purpose in cooler and wetter times of the year to consume the fuel without risking a catastrophic fire that is difficult to control. I just think that’s neat.
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.
