ScienceDaily (July 16, 2010) — When it comes to shoes, some women will go through hell for a pair of Jimmy Choos. But what effect does wearing high heels have on our bodies? Clinicians have known for a long time that if you hold a limb in a shortened position over an extended period, the muscles shorten. High-heeled shoes push our heels up, which made Marco Narici from Manchester Metropolitan University wonder whether wearing heels on a regular basis could shorten our calf muscles.
According to Narici, there was some anecdotal evidence that something changed because secretaries in the 1950s complained about discomfort when they took their heels off and walked flat-footed. “I thought it was an experiment which was inadvertently being done by women. What we could do was test high heel wearers to see if we could find some changes in the calf muscle,” says Narici, who publishes his results on 16 July 2010 in the Journal of Experimental Biology…

Here is a solid list of ways to live healthier and longer. Please note that with the exception of Genes, the other eight “secrets” are ones that we can choose.

There are some secrets to living longer. Many scientists have studied those who live the longest, looking to find similarities. Here are nine secrets that can help you live past the age of 90:
- Genes: One of the factors that figures into longevity is your genetic make up. Even though non-genetic factors are involved in living longer, the presence of certain genes might actually boost your chances. It was also found that siblings of centenarians were four times more likely to live past the age of 90 than those who had no siblings live so long. But, even though genes can help, they aren’t everything. Indeed, some scientists believe that longevity depends more on non-genetic factors. So, even if your family doesn’t have a history of living past 90, it doesn’t mean you won’t. Just make sure you make up for it with healthier practices.
- Eat fewer calories: One of the biggest Americans have is that they eat too much. Of course, what Americans eat does make a difference, but they should be eating fewer calories in general. Indeed, eating too much, and gaining weight, puts strain on your heart — and that’s even before the arteries clog up and you have a heart attack. If you cut back on calories, you can extend your life. Indeed, research from the International Longevity Center – USA finds that animals fed fewer calories live about 40% longer than those fed a great deal more calories. JAMA suggests that you should eat 25% fewer calories than you are now, if you want a better chance of living to 90. So, consider how much you are eating, and consider reducing your portion sizes.
- Eat colorful fruits and vegetables: It’s not enough just to eat more fruits and vegetables. The kind of produce you consume matters. Vibrant fruits and vegetables are the best when it comes to living longer because they have antioxidants. These are nutrients that actually stop damaging “free radicals” from harming your cells. Colorful produce that you should focus on include cranberries, cherries, broccoli, spinach, red apples, spirulina, blueberries and grapes. You should aim for five servings of fruit and five of vegetables. Replacing one red meat entree a week with a veggie entree can be a good first step. You will find that dark chocolate and red wine, when taken in moderation, are also good for aging and the brain. much more at the link
