WSJ looks at one couple in suburban Rochester, New York, who want to age in their own home in their eighties. AARP says about three fourths or 75% of Americans want to age in their own home in their eighties and nineties. And service providers including builders are actively working to help make the changes in homes that would provide a bedroom and full bathroom on the ground floor, and elevators other mobility enabling devices. Some like this Rochester couple are doing it themselves redesigning their homes.
