Our modern society is highly dependent upon the “system.” Not only do we rely upon utility services to bring us electricity, water and natural gas, but also on an incredibly complex supply chain which provides us with everything from food to computers. Without that supply chain, most of us wouldn’t know what to do.

This situation is actually becoming worse, rather than better. When I compare my generation (I’m in my 50s) to that of my children, I see some striking differences. In my generation it was normal for a boy to grow up learning how to do a wide variety of trade skills from his father, and seemingly everyone knew how to do basic carpentry and mechanic work. But that’s no longer normal.

If we extrapolate it back, we can see that my father’s generation knew even more – and my grandparent’s generation even more. Those older generations were much more closely tied to the roots of an agricultural society, where people were self-reliant. There are multiple skills they had which modern society no longer considers necessary.

But if we were to have a breakdown in society, those skills which we never bothered to learn would become essential. Those who don’t know these skills would either have to learn or die trying.

Here are 10 skills our grandparents knew that most of us have long forgotten:
