Washington (CNN) - As Vice President Joe Biden marks his 71st birthday Wednesday, speculation over whether he'll make another bid for the White House continues.
On a visit to Panama on Tuesday, Biden was questioned about a possible 2016 presidential run.
As Biden and the country's leader, Ricardo Martinelli, entered the presidential palace, the Vice President told the Panamanian president, who is term-limited, that he looked good, as people running for office never look good.
"You're going to be running next time," Martinelli replied.
According to a White House pool report, Biden chuckled, mildly abashed and quickly said, "Oh, we'll talk about that."
If Biden does make a third run for the Democratic presidential nomination - following bids in 1988 and 2008 - he would be almost 74 on Election Day 2016.
While Biden is the object of some presidential speculation, most of it is focused on whether former Secretary of State Hillary Clinton will run again. All polling suggests Clinton would be the immediate overwhelming frontrunner for the Democratic nomination if she does. Clinton will turn 69 shortly before the next presidential election.
Biden, by the way, received a birthday shout out from his boss.
"Happy birthday to a great @VP," President Barack Obama said in a tweet Wednesday that included a photo of the two men high-fiving on a basketball court.
