How America's change-leading generation has redesigned aging
America's baby boomers first came on the scene in 1946. They've been turning the world on its head ever since. Known as the country's greatest generation for leading change, baby boomers make up roughly 29 percent of the United States' total population - at about 79 million people. Over the years they've reinvented almost everything about the way America lives - from the music we listen to, to the cars we drive, to the technology we rely upon, to the way we age.
