3 easily recognizable signs of people with the ability to live long

Strong hands

Hand grip strength may reflect a person's health status and potential for longevity. Research published in Handgrip strength is an important indicator of a person's muscle mass, and older adults with less muscle mass have a higher risk of dying within 10 years, according to JAMA Network Open.

The analysis collected data from nearly 6,000 elderly people, of whom more than 13% had low muscle function, of whom 2.2% had obvious muscle atrophy and 11.1% had probable muscle atrophy. The conclusion showed that the risk of death from all causes in the next 10 years for elderly people with muscle atrophy increased by 93%.

Finnish scientists also published their research in the journal Gerontology. based on data from more than 340,000 people aged 40 to 108. The analysis found that individuals with stronger grip strength had a lower risk of non-communicable diseases and a 2% to 10% reduction in mortality.

Walk fast

Some people can walk fast and take long strides. Even in old age, they can still walk at the same pace as younger people. The analysis, published in the journal Communications Biology, found that fast walkers not only live longer, but are also biologically younger than the group that walks slowly.

The study collected data from more than 400,000 people with an average age of 56.5. The results showed that the group that walked quickly had fewer chronic diseases. Meanwhile, those who walked slowly had a higher rate of obesity.

The authors also found a causal relationship between walking speed and “leukocyte telomere length” — an indicator of physical aging. As a person ages, their cell telomeres become shorter. Fast walkers had significantly longer “leukocyte telomeres,” meaning they were more likely to live longer. The difference in “leukocyte telomere length” between fast and slow walkers was equivalent to 16 years.

Plump body but slim waist

Professor Shi Xiaoming and Professor Lu Yuebin of the Chinese Center for Disease Control and Prevention published a study on the relationship between body mass index (BMI), waist circumference and mortality in the European Heart Journal. Accordingly, among the elderly, the group that was slightly overweight but still had a slim waist had the lowest risk of death.

The study collected body data from more than 5,000 people over the age of 80 and made the above assessment. Waist circumference had a positive causal correlation with all-cause and cardiovascular mortality.
