Rogers's last years were devoted to applying his theories in situations of political oppression and national social conflict, traveling worldwide to do so. In Belfast, Northern Ireland, he brought together influential Protestants and Catholics; in South Africa, blacks and whites; in Brazil people emerging from dictatorship to democracy; in the United States, consumers and providers in the health field. His last trip, at age 85, was to the Soviet Union, where he lectured and facilitated intensive experiential workshops fostering communication and creativity. He was astonished at the numbers of Russians who knew of his work.
