Well it ain't no damn fruit cake, those things could live at the bottom of the ocean for 12 years and still be editable (of sorts I guess)

Now my concern is less about the package then the neighbor. I use to deliver papers when I was a kid. Noticed them stacking up at one of my deliveries. The old guy who lived alone passed away from a heart attack. I didn't think to tell anyone cause I was a kid and never thought about dying

you should call however the cops to check on him and the package
