Maybe living in the inner city. I know a great many people who feed their family through hunting. In my area, if there were to be a supply chain issue and food was hard to come by, knowing how to turn an animal to food is an important thing to know. I'd say that is likely more important that conn'ing a ship. Anyway, let's not get to pedantic. "A human should be able to feed themselves and their family."
That's the type of mentality that holds people back. Butchering a hog is just like processing a deer or elk. I've done all three and there is something about the experience that brings a greater feeling of respect and authenticity of where meat comes from and how certain cuts can be cooked.
