answer:It’s probably hard to quantify but based on what people do, what kind of work they’re engaged in, what they do in their free time would change things. If someone sits on a couch and plays video games, for example, and never watches the news, they are likely to hear less vocabulary words than someone that goes to work and speaks to others often. Likewise, someone that works in a fast food restaurant is likely to hear less vocabulary words than someone that runs a hedge fund (just some examples). So it’s pretty logical but of course there are many exceptions and anybody could find exceptions to anything.
