The "Outsiders"
The Amish community may be very different from their neighbors, but that doesn't mean they don't get along. Most Amish are usually welcoming of people who are curious about their lives. Many Amish groups travel to neighboring cities to sell their produce, baked goods, and hand-made goods to outsiders.
Modern Medicine
Even though the Amish tend to reject most modern things, medicine is not a part of that group. They are not opposed to using modern medicine, especially in the most serious circumstances. They do not have insurance, though, but the community usually pools funds together to help pay for sick community members.
