They aren't being drafted to go fight in Vietnam. The Russians aren't bombing our cities. The main health problem is eating too much food, not too little. Teens aren't even expected to have jobs anymore. (In my day, teens got jobs at 16.)
My dad volunteered in WW2. He expected to die in combat, as his cohort had an 80% casualty rate. 4 out of 5. Every mission meant holes in the airplane, and you stayed on course and took it. He helplessly watched men die. His best friend had his face burned off. When he returned home, he thought the concerns on the home front were trivial. After all, they were going to live another day.
