Chocolate is good for you! I've always said it is medicine but no one believed me :-) In addition to antioxidants it also has marijuana-like compounds, ha!
My great aunt is 97 years old. She spent her entire life eating whole eggs every day, whole milk, cream, butter and the FAT off meat. Never had a heart attack. Just recently she experienced a minor stroke and some TIAs. However, she did not grow up eating fast food or boxed food. Everything was always homemade and natural. There may be something to that in addition to outstanding genetics.
I think the main thing missing in our diet today is exercise, machines do the work for us.
Its hard to pump weight or ride a thread mill to me, But taking a bike ride or long walk is actually pretty uplifting, especially now that spring is here.
I bet your great Aunt stayed busy most of all.
