Few 89-year olds have their retirement home birthday covered by the local newspaper, but Peter Rodriguez isn’t your average 89-year-old. The artist founded San Francisco’s Mexican Museum, and still paints twice a week from his home at the Laguna Honda Hospital. In fact, some of Rodriguez’s most recent art pieces will be featured in the museum’s fall retrospective of his life and work. I asked Rodriguez if he knew the secret to longevity.
