Extract the answer to the question from the following context. Question: What part of Darwish's lifetime was spent abroad? Context: In 1966, Shmuel Yosef Agnon shared the Nobel Prize in Literature with German Jewish author Nelly Sachs. Leading Israeli poets have been Yehuda Amichai, Nathan Alterman and Rachel Bluwstein. Internationally famous contemporary Israeli novelists include Amos Oz, Etgar Keret and David Grossman. The Israeli-Arab satirist Sayed Kashua (who writes in Hebrew) is also internationally known.[citation needed] Israel has also been the home of two leading Palestinian poets and writers: Emile Habibi, whose novel The Secret Life of Saeed the Pessoptimist, and other writings, won him the Israel prize for Arabic literature; and Mahmoud Darwish, considered by many to be "the Palestinian national poet." Darwish was born and raised in northern Israel, but lived his adult life abroad after joining the Palestine Liberation Organization.[citation needed]
