Nebraska Public Power CEO Ron Asche has announced that he’s retiring from his position in February and moving to the Denver area in the dead of winter. But these days, retirement doesn’t necessarily mean the end of work: Asche will become CEO of United Power, an energy cooperative in Brighton, reports the Columbus Telegram. Whether you’re working or not, Denver ranks relatively high on the list of the most popular places in America to retire. Among cities with chilly winter climates, Denver finishes seventh but is otherwise buried—at 33rd in the overall rankings of 157 metropolitan areas—by warm cities in places like Florida, which holds 10 of the top 12 spots.

But the Denver Business Journal points out that if cities with relatively snow-less winters are excluded from the list, Denver finishes behind only Seaford, Delaware (number 13 overall); Barnstable, Massachusetts (number 14); Reno, Nevada (number 16); Chattanooga, Tennessee (number 28); Eugene, Oregon (number 29); and Salem, Oregon (number 31). The rankings, by, come as “an unprecedented three million Americans will turn 65” next year. But if you’re at that age, approaching it, or are older, how do you know if it’s time to retire? U.S. News & World Report tackles the questions surrounding retirement jitters.
