Yes YOU can.
I was a star ranked boyscout, I don't count.
But that's the point though, you don't need to be a boyscout to learn this stuff.
Just be like Nick and watch a stuffload of Survivorman if you want wilderness training lol. That's one of the few shows now where you can actually feel like a know-it-all after seeing one episode.
For the other stuff, yeah, you can still do on your own.
