Are you feeling more anxious than you used to?

If so, you're not alone.

Stress increased 18 percent for women and 24 percent for men from 1983 to 2009, according to researchers at Carnegie Mellon University in Pittsburgh, who analyzed data from more than 6,300 people. It's considered the first-ever historical comparison of stress levels in the country.

"The data suggests there's been an increase in stress over that time," says psychologist and lead author Sheldon Cohen, director of Carnegie Mellon's Laboratory for the Study of Stress, Immunity and Disease. The analysis is published online in the Journal of Applied Social Psychology.

Many Jersey shoppers say they are more anxious than they used to be.

"Everything is too fast," said one shopper, "everything has to be right now- now, now, and go, go go, go go."

Another man said, "Working all these extra hours- and it seems like when people leave, whoever is left gets their workload - so that's stressful."

A shopper standing nearby said, "Family, raising kids, economy, work, general things that everyone complains about - it's all stressful."

Another man said, "Worrying about work, and you know what's going to happen with my kids, next thing up - you know that can really throw me off…I'm thinking I'm not going to have enough time, of course everyone is concerned about their job…more is expected - even for those who have made the choice to stay home."

Someone else chimed in, "Right now probably I'm stressed out about the way people drive."

One woman said her stress comes from, "President Obama- because of the way that he's running our country -we're losing more and more money and it's becoming more and more of an entitlement country instead of people working…it's because of the economy - that everybody is just stressful- so it doesn't take very much to take in, and get you all hyped up."
