Whatever people or any other known institutes say, this is my take about coffee vs health.
we live once. then, no one knows how and when we will go.
there are people who smoked cigarettes for their entire lives and lived to 100.
and there are people (like my father) who died from Liver cancer at 59 without drinking a drop of alcohol in his life time. but he smoked, but rather than dying from lung cancer, he died from liver cancer.
it does not matter when you go or how you go.
just enjoy your life to the fullest and eat & drink in moderation and exercise everyday.
and then, whatever happens to you is not up to you. Nor it is up to coffee or alkaline or anything else.
And as for me, if it weren't for the coffee, I wouldn't have started my second mission in life and I have measured out my life with what kind of coffee I can drink and how much I can really enjoy.
