+(for Elision vs. Choice)
+Speakers of my generation are more likely to say "person" when sex isn't relevant, whereas older works (pre-second wave feminism?) would actually say "man" (or "woman"—see how anachronistic it feels to put the female option second and in parentheses?), presumably not because human nature has changed that much, but because of shifting cultural priorities about when sex is "relevant." (Modern speakers similarly frown on mentioning race (https://agentultra.com/blog/the-black-man-stopped-me/) when it's not relevant.)
