I haven't really prepared for any of this. Is there any point? With all you know do you think we can survive sit-x?
I'll be blunt, and say that a lot of people won't survive... but then, that's why we call it Sit. X in the first place.
But cheer up. Most of those deaths will be people who wouldn't or coudln't survive. (You're worried, so you probably aren't one of them.)
Some people will be killed in or as a result of the initial "event." That's just chance, their own bad/good luck, depending how you look at it.
Others who survive that will probably lose their will to live, or turn to suicide, simple because they don't have the strength to face such change.
Like the banker in "Alas, Babylon" who shot himself because his life didn't have meaning when he coudln't imagine life without they currency
system that made him important.
Still others will make it to the "wild" but die becaue of some injury or illness that is simply to strong to be cured.
But ultimately, "We" will survive. That being we as a species, but perhaps not me and you personally. Man has lived on the earth without technology
now; the only thing preventing a return to that is that we don't feel that we have to.
Really though, living in fear of dying is no way to go about it. It takes a lot of spiritual discipline, for some, but the best way to prepare for
anything is to accept your mortality--that way, NO ONE has any power over you.
