Having a father that was born in 1918, grew up in the Depression, was a coal miner as a teenager, fought in WWII, yadda yadda yadda, helped me learn most of those skills, not the technical ones like harddrives, et al, but the rest of the "self sufficient" ones were pretty much handed down at his knee....Even honing a knife (I think I have all his stones, which have to be over 50 years old knowing him)
My dad didn't call a plumber/electrician, etc unless he couldn't do it himself...even basic car mechanical skills.
The funny thing is that after the war he became a "suit" he was an accountant for a steel company, but he had a garden, a workshop, and pretty stocked garage.
Some of those things like "waxing the car" were my weekend chores...
If only my dad hunted though. there's a few skills I woulda liked for the umpcoming zombipocalypse.
I don't think half this stuff is taught anymore, even in cubscouts (where I learned some of the survival skills.)
It's funny that this book is such a big deal now...In a day where kids don't climb trees or even play outside anymore for fear of the predator snatching them up...
I grew up doing this stuff...And I'm only 43
