"Every day the increasing weight of years admonishes me more and more, that the shade of retirement is as necessary to me as it will be welcome."
-- George Washington, Farewell address, Philadelphia, 1796

Saving for retirement is a top cause of money-related stress, according to a recent Schwab Retirement Plan Services survey. Entering and living in retirement can be stressful, too -- in part because many people relocate during that time. Where do they go? Well, many move to be closer to family, while others simply seek a location more suited to their retirement lifestyle. Here's a look at the most popular retirement destinations for seniors. The towns were chosen by the folks at Money magazine, who cross referenced a list of locations that had the highest percentages of older residents with their database of "The Best Places to Live," which is based on factors such as affordable homes, a strong economy, low taxes, good healthcare access, and so on. The result is a list of places that have favorable conditions for retirement along with a lot of retirees who already live there.

Punta Gorda, Fla.

Florida is exceedingly popular with retirees, and Punta Gorda, which means "fat point" in Spanish, is a popular spot within it, featuring a rapidly growing population of 18,000-plus and a median age of nearly 66. It's situated near Port Charlotte in the southwest part of Florida on the Gulf coast and offers many waterfront homes and water-centric activities such as boating, fishing, and kayaking. (Its proximity to the water also has it vulnerable to hurricanes.) The median home price was recently $212,200 and the cost of living just a 5% above the national average. Punta Gorda offers the warm weather that many retirees seek and a small-town feel without as strong a tourist presence as many Florida towns have.
