Jimmy Carter Has Created New Model For Former Presidents

Jimmy Carter's recent health scare reminded us that the former president is still active at the age of 90. He returned home early from Guyana because he didn't feel well. Carter was in that country as part of the election monitoring work done by The Carter Center, which he formed in 1989.

The nation's 39th president says he feels fine now, so that gives Here & Now's Robin Young the opportunity to assess his life after the White House with historian Julian Zelizer, who says Carter has established a new model for what past presidents can do.
