Ok, so I found this site that calculates your life span by considering health factors, age, weight and family history. It took me about a minute and a half to enter the info and voila, I'm going to live to 89.
Now, the factors I had against me are weight and family history. Can't do much about genetics, but I can lose weight, which I want to do anyway. That way, I'll live comfortably into my nineties, which, of course, we all want to do. What fun would it be to deny our children their God-given right to change our diapers?
