The new year brings a new president - Donald Trump.
It may bring a new longest living president.
Right now, Gerald Ford lived the longest among our presidents - 93 years, five months and 12 days.
George H.W. Bush will celebrate his 93rd birthday in June and would pass Ford around Thanksgiving this year.
Jimmy Carter will also turn 93 in October.
Barack Obama leaves office in a few weeks at age 55. So he'll need to live until 2055 to reach 93 years.
