I dated a guy that KNOWS he's going to live until he's at least 95 because his grandparents did. Yet he won't acknowledge that his grandparents didn't drink martinis every night or smoked (we're no longer together) or chewed tobacco. His diet includes at least 10-12 cups of coffee, very little water, diet coke, processed foods and lots of gatorade.
My grandparents didn't live that long. Both of my parents have type II diabetes. My sister refuses to listen to anything I have to say about changing her ways. I know what my future looks like and its scary. All of them have bad habits and many of them are from our descendants. Hence, why I'm doing what I can now via Curezone.
I agree that people shouldn't blindly accept a belief about health or that this is what _____ are doing so we should be doing it to.
