Ammonia! Ammonia!
Imagine you're from a planet that can't stand the corrosive oxygen and has fluid ammonia instead of "poisonous" water.
Imagine you breathe nitrogen vapor.
Imagine your spaceship crashes on Earth, in the desert and you don't have a spacesuit.
You're in trouble! (from the New Yorker, R Grossman, 1962, translated in french for Time Life)
(The first time I saw this in 1968, I found it quite striking! But then, I'm sentimental)
Everything is relative.
