Secretary of State Hillary Clinton has said she will step down from her post if there's a second term for President Obama, and has suggested she's done with elected office. But speculation abounds regardless about a possible presidential run for her in 2016.

She'll only be 69, which is not that old in this day and age, ABC News pointed out to her husband, former President Bill Clinton.

"Looks younger to me every day," he laughed.

Asked if there remains a possibility she might run, the former president said, "I don't know, it's entirely up to her.  And I believe when she says she doesn't think she'll run, she's being completely honest with you."

What does he want?

"I want her to do what she wants to do," he insisted. "I'm glad she's comin' home, I miss her.  We have fun together."

"But here's what I know," he continued. "She worked hard on the '92 campaign.  Then we had eight years in the White House.  A lotta hard work, a lotta pressure.  Last year she runs for the Senate from New York.  Never run for office before.  She serves six years in the Senate, seven, then she starts runnin' for president…

"Everybody kept saying what a great political machine and all that; it was the first primary election she was ever in in her life, was when she ran for president," he continued. "And so she went through that.  And then she almost won, but she didn't.  She lost.  So immediately she then goes to work for President Obama in the campaign.   "Then he asked her to be Secretary of State, which came out of the blue for her," he recounted. "And she decides to do it.  So basically by early 2013, she will have put in 21 years of unbroken work on this.  And she wants to come home and decompress and relax.  And I believe that she's being absolutely honest with you when she says she doesn't think she'll go back into politics.   "Whether she does or not, who knows what will happen?" he went on. "I'll say what I've said all my life.  When I met her, I thought she was the most gifted person in my generation for public service.  I still feel that way.  I'm immensely proud of her.  But if she comes home and we do this foundation stuff the rest of our lives, I'll be happy.  If she changes her mind and decides to run, I'll be happy.  But that's light years away."

The former president made his remarks in an interview focused on Clinton Global Initiative University.
