I like to be as self-reliant as I can but that's difficult in this modern world and takes effort. Still, I work towards it as I know that one day those skills will make a big difference to me and those around me; people who are not properly prepared are in for a big shock. It's good to hear that you're moving the same way.
As for what you said about your grandfather's era, that's how it was all over the place and it was a better time to live I think; humans have lost their way thanks to greed and consumerism.
Anyway, thanks for your comments, I appreciate it.
