How long could you survive as the last person on Earth?
You wake up one day to the realization that you're the last man/woman on Earth. How do you survive?
What you'll need:
Water
* You'll need water for drinking, cooking, bathing
* Most bottled waters are good for 2-4 years after they are bottled. Could you find clean water if you had to?
Food
* Refrigerated/frozen foods would go bad within 7 days or less
* Most canned foods last from 3-8+ years after canning (depending on contents)
* Are you resourceful enough to farm/hunt/gather food?
Shelter
* Power to your home would eventually cease and if you were unable to find an alternative power supply
* No lights, air conditioning, heat, etc
Medicine
* You would eventually run into some sort of physical issues. Do you know enough to find medicine and self medicate yourself back to health?
Things to consider:
* You may have to travel if your hometown can't provide your needs
* You might want to get a pet dog for companionship
* You may have to protect yourself against wild animals
Do you think you could survive? For how long? What would your plan be?
