Photographer John Dugdale is joined by psychotherapist Robert Levithan to talk about a new class of AIDS fighting drugs. Both men have the AIDS virus; they are being treated with protease inhibitors. The treatment is helping them live normal lives. John Dugdale's photographs are collected in the recent book "Lengthening Shadows Before Nightfall." Robert Levithan conducts workshops called "Outliving AIDS" for those with AIDS who are living longer than expected.
