The most interestings things about him, atleast to me, are his longevity and length of his "retirement" (97 soon, 40 years since he stopped being the U.S. Pres) and that he's the last cold war US President. And of course the work that he has done after his presidency. Not a lot of interesting things about his life prior to his presidency, from during it or from the next ~15 years after it
Carter also wasn't a WWII combat veteran, unlike the two notable U.S. politicians in the list, Kissinger and Bob Dole:
Kissinger was put in charge of the administration of the city of Krefeld at the end of WWII and tracked down Gestapo officers, Dole was seriously wounded in 1945:
"Dole was paralyzed from the neck down and transported to a military hospital near Kansas, expected to die. Suffering blood clots, a life-threatening infection and a fever of almost 109 degrees; after large doses of penicillin were not successful, he overcame the infection with the administration of streptomycin, which at the time was still an experimental drug."
