People are not taught survival skills such as agriculture and how to gather wild edible herbs and plants.

And then there are archaeologists.

If civilization goes to pot, look me up for some good arrowheads and other tools. But better bring something good to trade; dollar bills may have deflated a bit.

Well, since I am probably about to buy books on gathering wild, edible, herbs and surviving off the land.I may be able to trade some wild, edible ,herbs (I may even learn about medicinal herbs while I'm at it) ,or maybe I could even trade in some of my books on hunting and gathering.
