LOUISVILLE, Ky. — Some people of faith worry they might forget about God, says geropsychologist Benjamin Mast at the University of Louisville. But what remains intact is the part of the memory that’s held longest, he added, which can include hymns and creeds that people may have recited for years. “They will remember how to say the Lord’s Prayer when they won’t remember anyone’s name,” said the Rev. Rebecca Church, a United Methodist pastor. Adelle M. Banks reports.
