As of today (March 22nd), Jimmy Carter is now the longest-living former U.S. president. Carter is 94 years and 172 days old, passing former President George H.W. Bush, who was 94 years and 171 days old when he died last November. The Georgia Democrat, who served only one term before being beaten by Republican Ronald Reagan in 1980, has spent the decades since leaving office on humanitarian, service and other projects, and won the Nobel Peace Prize in 2002. Carter was diagnosed with cancer in 2015, but after surgery and treatment is now cancer-free.
