Aging has changed in the 21st century. The cliches are true: "40 is the new 30," "50 is the new 40." And when it comes time to retire, your retirement won't look like your grandfather's retirement. So why do we still view it the same way?

Signature Wealth Strategies CEO Chip Munn believes there's a need for a new retirement model, especially since many of us will still be working in some capacity after we "retire," whether out of a desire to stay active, or because of a shortfall in retirement savings. Munn calls it a "remixed retirement," which is also the title of his newest book, The Retirement Remix: A Modern Solution to an Old School Problem. He recently discussed his ideas about how retirement has changed, retirement readiness, and steps workers and employers can take to keep an aging workforce productive and engaged.
