Two of my great grandparents lived to advanced ages, and they were short and ate a diet that would not lead to AA in their cells. Two grandparents who are still alive, and now quite old (early 90s, mid 80s) are taller and suffer much more from "chronic disease." They take a lot of drugs for various conditions. They most likely had Mead acid in their cells, but sometime over the last couple of decades it started to get replaced by AA. |
