Again,with all my respect, you are mixing things: what you desscribed was field craft, campcraft, however you wishto call that-It is NOT SURVIVAL!!!!
In a survival situation you are struggling to save your life. Sure, those skills we learned when kids help improvise tools and devices that will make your task easier, so keep improving yourself on them- it is both fun and useful.

If I know how to make a blade? oh yes, I do know that.and thousands of knots, , and first aid, and field cooking, and navigation by the stars, and reading topo maps, and other things. No, I don't play harmonica, but drums I can play decently well.....
