When Walters notes Clinton would be 69 in 2016 and asks if her age is a concern, Clinton replies, “It really isn’t. I’m thankfully, knock on wood, not only healthy but have incredible stamina and energy.”

Clinton adds, “I just want to see what else is out there. I’ve been doing this incredibly important and satisfying work in Washington, as I say, for 20 years. I want to get out and spend some time looking at what else I can do to contribute.”
