ὁμιλία καὶ ὕπνος μόνοι δείκνυνται οὖσα θνητός.
-translation by classicsenthusiast
"Sex and sleep alone make me conscious that I am mortal."

(FYI this is actually a “quote” misleadingly attributed to Alexander the Great, which stems from this section of Plutarch, wherein he states that:
ἔλεγε δὲ μάλιστα συνιέναι θνητὸς ὢν ἐκ τοῦ καθεύδειν καὶ συνουσιάζειν.”
or: “he said that he is most conscious of his mortality when sleeping or having intercourse.”)
