Should you not desire to read my nonsensical theoretical backdrop story, skip to the bold*
Assume that, hypothetically of course, some sort of zombie/nuclear/yellowstone/asteroid apocalypse took place in the near future and in the process of said apocalypse, all of modern technology (including weapons, shelter, household items, etc.) and stored food were destroyed. Further, the planet recovered immediately and quite miraculously from whatever manner of damage it sustained from the cataclysmic event as well as 250 years of human industrial activity. That means no irradiated soil, no polluted water, no toxic fumes floating in the air, no ferocious 3-headed mutant cows roaming the plains--nothing beyond natural forces and natural creatures. Effectively, the earth has been returned (marginally) to its natural state circa 200,000 years before present (date of the "mitochondrial eve," coincidentally). Our particular celestial body may be functionally optimally once again, but humanity has been nearly eradicated, leaving only 10-12,000 members of our species alive.
Assume you are one of the lone survivors. You are completely without modern tools and amenities, so how will you live? What will be your first objective? Do you think you possess the skills and mental fortitude to be a true paleolithic 'caveman?' Or will you just be food?
