We had the perfect marriage. We traveled all over the world, especially to places where we had to sleep in tents. We loved roughing it. We climbed in the Himalayas, floated down the Amazon, and got arrested by the KGB. I had trouble keeping up with this bright, charming, active man. Then he began to change imperceptibly at first. This is the story of living with his dementia and remaining in love and reasonably happy. As I say in the book, brain cells may die but love does not have to.
