For the first time, scientists have found a genetic mutation that appears to offer a measure of protection against some of the biological effects of ageing.
And, as far as we know, it looks like the only community in the world known to harbour it is an Old Order Amish community living in Indiana.
The mutation can occur on one or both copies of a gene called SERPINE1. It’s known that when both gene copies are mutated, it can lead to a rare genetic bleeding disorder — and the Amish community in question is susceptible to it.
