A student who had graduated and started his own business came to visit me on Teacher's Day. He was very unhappy because the daily clinic was so unchallenging, half of them were overweight children and half were overactive children. He said, "I told the parents to be disciplined about their diet and not to give them snacks, but they couldn't stick to it. When the kids argued, they surrendered right away. I told them that their tastes when they were young would affect their choices when they grew up. Those who ate fried chicken and hamburgers every day when they were young would, of course, give preference to fried chicken and hamburgers when they grew up.
