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".
Kettle on.
