I don't know much about what an Amish lifestyle entails but I have to imagine their limited or non-existent exposure to modern carcinogens helps as well. I think of all the awful things I've been around only to learn later it could adversely affect my health.

Or maybe the cases just aren't recorded.

Deaths are always recorded, though. And Amish men live longer than non-Amish men, indicating that they are overall healthier.

The Amish are also overall happier. Maybe that contributes to the longer life?
