Healthy
A curious rule of Amish society claims to have improved communal well-being. Amish people have a zero-tolerance stance for drinking and smoke, and statistics show that they have a 40% lower cancer incidence than most of the planet. Given the benefits, maybe more citizens can follow this example!!
Fashion
Since the Amish place a great value on modesty, they should only wear a limited amount of clothes. To maintain them appearing traditionally accurate, it is against school policy to wear brightly colored or special style clothing.
