Lets say that today, something catastophic happened. Be it nuclear war, an asteroid hit, whatever. And it ended life as we know it. No electricity, no medicines, no computers (argh).
To eat, you finished what was in your kitchen. Beyond that you had to find whatever you could to eat. Winter is coming...no fuel will be available. Do you have a woodstove? Wood? The means to get some wood? Saws, axes, can you start a fire without matches?
Your wife is pregnant. Can you deliver the baby?
Are you armed? Do you have enough ammo? Are you good with guns...firing, cleaning, repair. WHen the ammo runs out could you make weapons? Do you have tools?
Personally I think the people with the best chances would be country folk. Small communities that could rely on one another. My guess is ,in the first 6 months most of the world would starve to death. Mostly in the cities. After that disease would claim the rest. Communities would'nt allow strangers in, due to disease and distrust. Someone would be left to carry on Im sure, providing radiation wasnt involved.
Frankly...I dont think Id make it. I dont think Id want to live in that world. I depend on society. Without it Id surely perish.
It seems as technologically advanced we are..the simple things that were the lowest tech at one time, have been forgotten. Take the sword for example. Could you make one? Where do you find iron ore? How would you melt it? Form the blade? All the little things of every aspect of basic tools,farming etc. We would be worse off than the middle ages. Which in my mind was probably one of the most miserable times there was. So if it will be that bad, I think Id rather the asteroid fall on me.
