I also read some time ago that chubby ol’ grey haired ladies just seem to go on and on and on like the energizer bunny.
As all my grannies were chubby and lasted in sound mind well into their 90s. Works for me.
My very thin great aunt lived to 104, her brother, my grandfather her brother dies at 100 and their aunt lived to be 106. I think it is in the genes. I hope I got them, except I am not as thin as they were.
