Both grandfathers died of cardiac events in their late 50's, both grandmothers lived into their mid 90's.
My father died at 83 of pancreatic cancer, Mom at 94 of congestive heart failure.
Both of my brothers checked out at 73, one four years after the other....of cardiac failure.
None of them took very good care of their health and wellness........poor diet, sedentary lifestyle and overweight. Dad was a secret drinker and we all pretended we didn't know.
I however have never been overweight, eat a Mediterranean diet and do 30 minutes of moderate cardio exercise every night and about 15 minutes of moderate upper body muscle building every morning. And quit a heavy drinking habit 22 years ago.
