This is not because we're hungry. This is because our small intestine is actually a huge neat freak, and it takes the time in between digestion to clean everything up, resulting in those eight meters of gut, really, seven of them, being very clean and hardly smelling like anything.
Esto no es porque tengamos hambre, sino porque el intestino delgado es un gran fanático de la limpieza, y se toma un tiempo después de la digestión para limpiar todo, dejando esos ocho metros de intestino, bueno, siete en realidad, realmente limpios y sin ningún olor.
