You’ll know it alright. Your feet will tell you right before whatever is over your head (hopefully nothing but sky) comes crashing down. But then again, we are already being sold the “Chicken Little” story in its newer version called “Climate Change”. Funny thing is, my climate changes whenever I walk outside my house.
You are supposed to stand under door jams where you are under part of a wall. Can’t go outside because you could get electrocuted by live wires; and if gas lines break with live electrical wire there could be one big blast anyway.
