The benefits of regular exercise are well documented but there's a new bonus to add to the ever-growing list. New researchers found that middle-aged women who were physically fit could be nearly 90 percent less likely to develop dementia (失智症) in later life and is they did, it came on a decade later than less sporty women.

Lead researcher Dr. Helena Horder, of the University of Gothenburg in Sweden, said: "These findings are exciting because it's possible that improving people's cardiovascular (心血管的) fitness in middle age could delay or even prevent them from developing dementia."

For the study, 191 women with an average age of 50 took a bicycle exercise test until they were exhausted to measure their peak (最大值的) cardiovascular capacity. The average peak workload was measured at 103 watts. A total of 40 women met the criteria for a high fitness level, or 120 watts or higher.

A total of 92 women were in the medium fitness category: and 59 women were in the low fitness category, defined as a peak workload of 80 watts or less, or having their exercise tests stopped because of high blood pressure, chest pain or other cardiovascular problems.

These women were then tested for dementia six times over the following four decades. During that time, 44 of the women developed dementia. Five percent of the highly fit women developed dementia, compared to 25 percent of the women with medium fitness and 32 percent of the women with low fitness

"However, this study does not show cause and effect between cardiovascular fitness and dementia it only shows an association. More research is needed to see if improved fitness could have a positive effect on the risk of dementia and also to look at when during a lifetime a high fitness level is most important" She also admitted that a relatively small number of women were studied, all of whom were form Sweden so the results might not be applicable to other groups.

For nearly a decade now, Merebeth has been a self-employed pet transport specialist. Her pet transport job was born of the financial crisis (危机) in the late 2000s. The downturn hit the real estate (房地产) firm where she had worked for ten years as an office manager. The firm went broke and left her looking for a new job. One day, while driving near her home, she saw a dog wandering on the road, clearly lost She took it home, and her sister in Denver agreed to take it This was a loving home for sure, but 1. 600 miles away. It didn't take long for
Merebeth to decide to drive the dog there herself. It was her first road trip to her new job.

Merebeth's pet delivery service also satisfies her wanderlust. It has taken her to every state in the US except Montana Washington, and Oregon, she says proudly. If she wants to visit a new place, she will simply find a pet with transport needs there. She travels in all weathers. She has driven through 55 mph winds in Wyoming, heavy flooding and storms in Alabama and total whiteout conditions in Kansas.

This wanderlust is inherited from her father, she says. He moved their family from Canada to California when she was one year old, because he wanted them to explore a new place together As soon as she graduated from high school, she left home to live on Catalina Island off the Californian coast, away from her parents, where she enjoyed a life of sailing and off-road biking.

It turns out that pet transporting pays quite well at about $30, 000 per year before tax. She doesn't work in summer; as it would be unpleasantly hot for the animals in the car; even with air conditioning. As autumn comes, she gets restless-the same old wanderlust returning. It's a call she must heed alone, though. Merebeth says, "When I am on the road, I'm just in my own world. I've always been independent-spirited, and I just feel strongly that I mush help animals. "
