Hell yeah. Nothing says multitasking like leveling up multiple skills at once in Project Zomboid. I usually worked on Carpentry--dismantling stuff--while listening to the TV, but you can do all sorts of activities within earshot. Sew your clothes, fashion a wooden spear, or cook that bunny rabbit you caught this morning. I will say that I noticed reading and TV didn't always work together, which is the ultimate disappointment. Reading a book takes forever in Project Zomboid, and being able to get XP from a book and a show at once shouldn't be a problem. All I can say is that sometimes it worked, and sometimes it didn't. TV shows are usually too short for you to get much reading in anyway, so focus on other skills to improve while watching TV.
