Suffering from early-onset Alzheimer’s, 56-year-old Peter Marshall has forgotten much of his past, even the fact that he is married to the woman who lives at home with him and takes care of him. The mind may be confused, but not the heart -- Marshall fell in love with his wife, Lisa, all over again and, having no recollection of his previous wedding, proposed to her once more. A surprised and happy Lisa accepted, and they had a perfect wedding. “I’m the luckiest girl in the world. I [got] to do it twice,” Lisa said.
