As Americans start to live longer, well, they’re getting older. According to the Washington Post, Americans over 65 make up 15 percent of the current population. That number is projected to rise to 24 percent by 2060. But living longer also requires some strategic planning. Chances are that 5,000-square-foot dream home — not to mention the boat and garage full of toys — won’t seem so practical during your golden years. That’s why more seniors are decluttering and downsizing.
