A church filled with nuns. Most of them just die in the middle of the night but it depends on the convent they are in. (I don't know how to spell it, just bare with me). The nuns in a certain area seem to do very well, all living to over 100. They also seem immune to Alzheimer's in the area. 40% were supposed to get Alzheimer's, but never did. I should write a hub about those nuns.
