I find this kind of thing the be very instructional!The medical community may be able to learn something by tracing the covid among them. They do bipolar studies among them because they only marry among themselves and have no divorce so they are a good choice for genetic research.
The generic diseases among the Amish are different then the ones among Mennonites. Mennonites have a kidney disease which the baby eventually dies because they don't live long enough to do a transplant. It has been traced to the Burkholder relation.
Thanks for sharing it with us
