My grandparents on my mother's side were farmers and both lived into their mid 90's without diabetes. My fathers's parents were city dwellers, my grandpa was a civil engineer and my grandmother was a seamstress. They died at 86 and 100, again no diabetes. I am one of 6 children, the only one with diabetes so far. My parents are both alive and 91. My dad just was dx'd with diabetes 2 years ago at the age of 89 from taking prednisone for many years. So I don't think I can blame my ancestors, they seemed to live a pretty healthy life.
