Lets say your being chased by zombies/monsters/aliens/army of angry kittens, and you do something (like holding them off, shutting the air lock or going down with the ship) that saves your group of friends or family, but kills you. You get one look back at them before you die, what do you say to them?
I would just simply smile and say: "Keep running."
