The Martian

I’m stranded on Mars.
I have no way to communicate with Earth.
If the Oxygenator breaks down, I'll suffocate.
If the Water Reclaimer breaks down, I'll die of thirst.
If the Habitat breaches, I'll just kind of explode.
If none of those things happen, I'll eventually
run out of food and starve to death.
I'm screwed.
