A new way to measure the speed of aging
You can measure the speed of aging with a hand grip. According to researchers, it’s all in the handshake – particularly the strength of the hand grip. New research indicates that the strength of your grasp may be the best way to measure your true age.
In a recent new study, researchers Serguei Scherbov and Warren Sanderson have shown that hand grip correlates to other aging indicators such as future mortality, disability, cognitive decline, and ability to recover from hospital stays.
The researchers believe that the conventional definitions of old age are out of date. eg it is often considered that old age starts at 65. But life expectancy has changed dramatically and there have been considerable advances in geriatric medicine. Professor Sanderson suggests that we should consider people as old when their remaining life expectancy is less than 15 years.
For this new research, over 50 published studies from all over the world were used. “Hand-grip strength is easily measured and data on hand-grip strength now can be found in many of the most important surveys on aging worldwide,” says Sanderson.
The study also shows how such a test could be used as a measure for aging to compare different population groups.
This new research is all part of a world wide attempt to better define again based on other characteristics than just chronological age. For example, health, family history, education, and lifestyle are also important.
The speed of again can also be measured in different groups within society. From there, it should be possible to identify the factors that are impacting on the group which ages faster, and to put policies into place which would make longer life attainable for most.
