Financial expert Suze Orman joins “CBS This Morning” co-host Gayle King to discuss what people approaching retirement need to do to be financially sound. Orman explains why, thanks to increased life expectancy, the best age to retire is not 65 - but 70 years old. Plus, she shares why she decided to step back from her successful career and retire at 65. Orman says she wrote her latest book, “The Ultimate Retirement Guide for 50+: Winning Strategies to Make Your Money Last a Lifetime,” because there isn’t enough time later in life to make financial mistakes. Plus, hear what common financial mistakes people are making - including what she has to say to parents who are helping their children financially.
