If you want to look and feel younger than your years, maybe you need to move to another city. Like Salt Lake City, San Francisco or Austin, Texas.

Those are the top three cities in RealAge.com's list of the 10 "youngest" cities in America — metropolitan areas with such healthy lifestyles that on average their residents are physically at least two years younger than their chronological age — and many are years younger than that.
RealAge is a website cofounded by Michael Roizen, M.D., chief wellness officer of the Cleveland Clinic, and internist Keith Roach, M.D., with Weill Medical College of Cornell University. The site offers an online health assessment that has been taken by 27 million people since 1999. Respondents are asked about their health habits from sleep to smoking to stress. Sample information from 1,000 men and women in each of the 50 largest metropolitan areas was used to come up with the 10 "youngest" and "oldest" cities, based on the health of their residents. The data were adjusted for age differences, so that a city that attracts retirees wasn't penalized when compared with a college town full of young adults.
On the other hand, residents of Knoxville and Nashville may need to start worrying. Those two Tennessee cities are numbers one and three on the list of metro areas most likely to make you old before your time, with Greensboro/Winston-Salem/Highpoint, N.C., coming in second.
Go west, stay young
Half of the youngest cities are in the West, where some might argue that a milder climate makes outdoor exercise easier. However, Boston, Washington, D.C., Denver and Minneapolis are also on the young list — cities that get more than their fair share of severe weather. So it can't just be a weather thing.
"There is a higher level of exercise in Western cities, which affects their rates of cancer and heart disease," Roach says. But what makes more of a difference is living in cities "with good public transportation and where it's easier to get to places by walking. Those cities tend to do relatively well."
