Science is always looking for ways to predict our lifespan. In the past, these predictions have generally been based on age and sex, and they don’t often consider lifestyle factors. Some more recent studies into lifestyle factors have shown interesting results.
1. Fast walkers live longer
Stephanie Studenski, M.D. and her coworkers at Pittsburgh University studied 34,485 people over the age of 65. They found that among those of the same age and sex, the faster walkers were expected to live longer. This is because walking is very effective in burning calories and it helps to maintain co ordination. Walking also promotes and supports the relationship between the cardiopulmonary, cardiovascular, nervous, and musculoskeletal systems. These results show that gait speed is a good indicator of life expectancy.
2. Eating your way to longevity
“Our kitchen is our pharmacy,” says Mina Dobic, a state-certified nutritional adviser in Los Angeles. “When you eat well and you also live well, then you live a longer life.” The American Heart Association and American Cancer Society both agree diets that are high in fiber and low in saturated fat and cholesterol help to prolong life. Chinese medicine divides food into hot-natured, or “yang” foods, and cold-natured, or “yin” foods. If the consumption of food from each group is not balanced, this can result in a negative impact on the overall health of your body. Vitamin B12, which is only found in animal products, is especially important in promoting longevity.
3. A baby face indicates longevity
Professor Kaare Christensen, from the University of Southern Denmark, found that a younger appearance may be a factor in longevity. Christensen carried out physical and intelligence tests on 913 sets of 70-year-old Danish twins. Part of the research involved taking photos of each twin. They asked 3 groups of assessors, made up of other scientists, to rate the perceived age of the study participants by looking at the photos. None of the assessors were aware of the real age of any of the twins.
Afterwards, according to the British Medical Journal website, researchers tracked death records over a 7-year period. The team found a strong connection between the perceived age and the longevity of a person, as reported in the Daily Mail. They discovered that the older-looking twin was more likely to die before the younger-looking twin.
4. Eating less enhances longevity
Scientists believe that eating less will increase your life span. An ongoing study shows that low calorie diets help increase the lifespan of mammals.
