If I am trapped in a situation where I am going to be bored for a while, such as having to sit in a waiting room, I have a mental exercise where I create a doomsday plan. Sometimes it will be a zombie apocalypse, but it could be nuclear war, a large natural disaster or even something more immediate like making an exit strategy if someone runs into the room with a shotgun.
I'm not a prepper or anything like @pembo, it's just a thing I've done for as long as I can remember. So yeah, what is your doomsday plan, whatever your chosen doomsday scenario may be?
Hard mode: it can't include the words "Winchester" or "pint".
Get to my parents sailing boat, live in peace and quiet on the sea while the plebs of this world battle with zombies and such.
