Centenarians are some of the most fascinating people alive and we’re not the only ones who think that way.

Steve Franklin has learned the lesson that if you really want to understand what it takes to live to 100 years, why not ask the people who have done it?

He’s gathered what he’s learned in his book, “Celebrate 100: Centenarian Secrets to Success in Business and Life.”

Steve tells us some of the things he’s picked up from the more than 500 centenarians he interviewed for this project and shares common denominators that he believes helped them to get to this point. Plus, find out the three principles you can adapt into your life today (that are free and easy!) that he says are essential for a good quality of life for the entirety of your life.

And what do most centenarians credit with getting them to 100? Here’s a hint: it’s not your genes.
