Yep, she is still pretty at age 68.
And although she was anti-war she did indeed live by her principles. She was no Jane Fonda:
From: http://en.wikipedia.org/wiki/Joan_Baez
During the Christmas season 1972, Joan joined a peace delegation traveling to North Vietnam, both to address human rights in the region, and to deliver Christmas mail to American prisoners of war. During her time there, she was caught in the U.S. military's "Christmas bombing" of Hanoi, North Vietnam, during which the city was bombed for eleven straight days...
Her disquiet at the human-rights violations of communist Vietnam made her increasingly critical of its government and she organized the May 30, 1979, publication, of a full-page advertisement (published in four major U.S. newspapers) in which the communists were described as having created a nightmare, which put her at odds with a large segment of the U.S. left wing, who were uncomfortable criticizing a leftist régime. In a letter of response, Jane Fonda said she was unable to substantiate the "claims" Baez made regarding the atrocities being committed by the Cambodian Khmer Rouge.
It would help if she was a bit more careful and thoughtful and used a bit more common sense for the sake of her own safety and her fans.
