This would be a fun scenario. Except for being alone the rest of your life.
I'd head into town, gather up some supplies, raid the headshop in my town, and head back to my apartment. Pack up all my belongings and find a nice suitable home better than my apartment. I'd have to figure out how to keep food cold since there would be nobody to run the electric. So dry canned food for a while.
I would then plant a big field of marijuana.

This sounds like that movie with will smith thats coming out soon.
