It is generally accepted that life expectancy is only 25% dependent on the set of genes that our ancestors gave us at birth.. Otherwise, it is determined by habits and lifestyle..

But how intriguing are these 25%! Agree, it is curious to know what program nature has laid in us and how many years it has measured.

The signs of a long-liver were described in ancient Indian and Chinese treatises on medicine.. Certainly not all. Modern research has significantly expanded and scientifically substantiated this list..

Handshake.

“The stronger the handshake, the longer a person will live” - with these words ended the report of British scientists based on the results of studies that they conducted for 25 years..

I have already talked about how closely the work of the brain, the main organ of longevity, is closely connected with the movements of our body.. Please read this article.

The strength of the hands is a clear indicator of the active and synchronous work of both hemispheres.. While lethargy speaks of mental decline and the presence of cardiovascular pathologies. The muscles of the hand are closely connected with large vessels: a decrease in their elasticity immediately affects the tone of the muscles of the hand.. And since muscles are also the main storage of protein, and one of the main regulators of blood sugar levels, it is not surprising that a weak handshake can be safely regarded as an increased human vulnerability to various diseases.. There is no question of longevity in such a situation..

earlobes.

But the ancient Chinese scientists considered the earlobes to be an indicator of longevity and heart health.. In the treatise " Term of life" , the lobes are called the mirror of the cardiovascular system, and the folds on them are an indicator of violations in its work.

Research by scientists at Fudan University in Shanghai confirmed the validity of ancient texts: the skin on the earlobe is extremely sensitive to even the slightest changes in blood flow and, if it is not a congenital defect, serves as a marker of high blood pressure, the risk of developing atherosclerosis, stroke and coronary heart disease.

healthy gut.

The well-known Russian immunologist Ilya Mechnikov, at the beginning of the 20th century, wrote about a direct connection between the state of the human intestinal microflora and his life expectancy..

Modern research by a group of scientists from Canada, the USA, Italy and Japan proved Mechnikov right.. The intestinal microflora of centenarians is significantly different: it contains more beneficial bacteria, and their diversity practically does not decrease with age..

The good news is that gut microflora can be restored. And how to do it, you can read in this article..

Moles.

The abundance of moles on the body is often perceived by many as an alarming indicator.. And there is certainly some truth in this..

But all the more surprising were the results of studies by American geneticists published 5 years ago in the journal Cancer Epidemiology Biomarkers \u0026 Prevention..

It turns out that the presence of a large number of moles is evidence of a genetic mechanism of protection against rapid cell aging inherited from long-lived ancestors.. And the first sign is confirming - the length of telomeres, which is many times higher in people rich in moles..

Optimism.

This is perhaps the most unexpected, by nature, sign of longevity..

Professor of cognitive neuroscience at the University of Chicago Emily Rogalsky published the results of her research several years ago..

It turned out that optimism is one of the main signs of a long-liver, since the ability to easily look at life and not bother over trifles is the result of the presence of rare spindle-shaped neurons in the brain, which were discovered by the Austrian neurologist Konstantin von Economo and named after him.

They strengthen connections between different parts of the brain, help maintain its neuroplasticity, protecting the entire body from aging..
