This predictive world site is pretty cool, but mostly inaccurate. It took some Facebook info and whatever else it could find , but if I need to go in and edit almost every category, it's kind of useless. And even then it was so variable it's not funny.
If you change the salary from say $50 to $200 the life expectancy goes up 10+ years. And they say money doesn't buy happiness. Well according to the predictive site just making more money means living 10+ more years.
