Eunice Kennedy Shriver, the sister of President John F. Kennedy and the founder of the Special Olympics, is in critical condition in a Massachusetts hospital. The 88-year-old is "surrounded by her family at Cape Cod Hospital," the Associated Press reports. Governor Arnold Schwarzenegger, the husband of Shriver's daughter Maria Shriver, is also at her side. Shriver has nineteen grandchildren and is the only woman to have appeared on a U.S. coin during her lifetime. She received the Presidential Medal of Freedom in 1984 for her efforts with the disabled.
