On the long lived side...my dad is 81, and he's still going pretty strong...his 2 older brothers are 91 and 89. My paternal grandparents lived to be 93 and 91,
On the short lived side...my mom passed away at 67 (lots of health issues, but her ultimate cause of death was congestive heart failure). Her father died at 47 (cancer). Her mom died at 72. My mom's sisters died at 22 (kidney failure) and 74 (cancer).
So I guess for me it's a crap shoot ...
