Hi, Chuck! When I have a work set in this world, I struggle w/ how much pop culture (music, social/political topics, clothing, hair styles, phones) to include. I try to keep my primary audience in mind, but I don't want readers outside that audience to feel like old geezers or like I'm an old geezer. When I don't include anything of that sort, the world doesn't feel as fleshed out as it should. Any advice?
