A hands-on perspective, seeing the body parts as they actually exist, with mesentary and connecting tissues, where the various ducts and tubes lie, helped me, as an amateur, process food animals for my personal consumption. I've done rabbits, pigs, sheep, goat... and assisted with cattle. (They're too heavy without a true winch-lift to do solo.)
Though not a necessity per se, it's comforting to know I know how should that change.
