Every morning, Phil and Carol Germaine sit in their family room, read names of friends from last year’s Christmas cards and pray for them. Carol started forgetting who Phil was a year ago. “Where is my husband?” she would ask. Phil resisted giving her an identity bracelet, below, because he thought it was demeaning, like tagging a dog, but he got her one after she wandered from home.
