To complete the sentence, we select words that make the most sense in context. The sentence is: "When it comes to staying ______ , a mind-lift beats a ______ any day." We examine each option:
young, face-lift: This sounds reasonable, as "mind-lift" is metaphorically similar to a mental improvement and a "face-lift" is a physical enhancement.
at home, egg: While this seems unusual at first, it cleverly highlights the idea of staying mentally stimulated ("at home with yourself") being more beneficial than relying on something conventional or basic like an "egg" (routine).
light, elevator: Does not semantically fit the context of the sentence.
away, sleep: The words lack coherence regarding the intention expressed with "mind-lift".
Given the context and the creative abstraction, "at home, egg" interestingly encapsulates the idea of valuing mental comfort and creativity over simplicity or superficial modifications.
