Stanford project suggests longer, healthier lives are possible

More Americans are living to their 80s, 90s and beyond, unthinkable just a century ago. Most say they expect to live to their 80s or longer, and want to live to 100 if they can do so in good health.  

But the policies, products and personal behaviors to support such lives are not yet widespread, according to a new study by Stanford’s Center on Longevity.
