Genetics, diet, exercise. 

All of these factors have shown to be the key determinants of longevity. 

But researchers discovered another way to predict our life spans: our zip codes.

 In some cities, a few blocks could increase the likelihood of dying 30 years earlier. Where we live determines how we live. And how we live matters more than you might imagine.

 No matter where we live, we all wish for long, healthy lives for our family, for our loved ones, for our children. But even if the odds are in your favor, predictions are only part of the picture. 

We live in a world where everything can change in the blink of an eye. You could be on top of the world one minute but you never know when the rug might be pulled out from under you.

 When that happens, which it inevitably will, all you can do is hold on. 

And hope it won't end you.
