Sarah Morse, 72, lives in San Francisco's Fillmore District. She and her husband have three grown children and six grandchildren, and they enjoy visiting their renovated 1956 Airstream, parked on the hillside of a friend's Sonoma County vineyard. Morse is also a breast cancer survivor. After being diagnosed at 59, she was certain she didn't have a chance of surviving but swore that if she did, she would find a way to help others.
