I've a weight problem all my life. My parents bought me "huskies" while I would grammar school. I wasn't a very active kid. My parents always provided 3 good meals personally daily. School lunches were actually nutritious in those days. They weren't anything like they are now with pizza, tacos, hamburgers, sausages, fried potatoes, sweet sodas and all forms of chips and desserts. I hear french fries would be the main course especially with school girls. Today's kids do not have the opportunity. Before commencing battle a soldier needs to prepare. To wear the correct armour and get their hands on a shield and sword. The armour protects from harm and the sword kills the not so good guy. You also need to be fighting fit. It's the same whenever you battle against yourself. You need protection from dangerous illusions also to be with right knowledge and understanding.
