Obviously you gotta look out for any news, landing pages, texts, water cooler conversations, TV in general, electronics, opening your eyes, and the town crier but how long could you realistically go?
Assuming you don't go to your bunker in the woods I guess.
I'm gonna try, but my guess is Thursday when I discord with my friends. It'll come up, I'm sure.
Practically impossible for me not to find out without going into complete isolation.
