A little background. You know I'm 70: No secret. I was raised in a suburb of a large Midwestern city that had no city water, so when our suburb was built (started late 30s, our home built 1940, I was born '43) so everything was set up around community wells, about 12 to 15 homes to each well. So, no fluoride in the water. Also the Gene fairy was unkind to both sides of my family. Both my parents hat their teeth removed in their early 30s, before I was born. I never knew them without dentures.
