“We’re old! What’s wrong with that?” asked photographer Nancy Rubin in a recent California magazine article. A new exhibit — featuring Rubin’s photos, with interviews by writer Cynthia Overbeck Bix — evokes this question, and others, while challenging existing views on aging. For the exhibit, Rubin, a former teacher at Berkeley High, photographed a dozen subjects, many of whom have embraced a new pursuit in their retirement. Their stories — and photos — will be on view in the exhibit, called Reframing Aging, in Doe Library through March 2.
