40 years old
Back then they used nails. They do pop after decades. This is VERY common. In our house, we intentionally followed along a stud and popped as many as we could find. Then we inserted a screw on both sides and removed the nail. We pre-emptively popped them all for fear that more would become visible over time. Then you need to do drywall repair. Mud the hole, knock it down, mud again, sand, fill, sand, prime the spots and paint. If the nail pops are along the perimeter, crown moulding can cover some. We did one room at a time. It worked! No more nail pops for 20 years now in this old house!
