Scientists around the world are trying to discover the secret of longevity. Researchers have found that human life expectancy is only 25-30% determined by genetics. The remaining 70-75% are attributable to external factors and the lifestyle of a man or woman. Whether a person is destined to live 100 years can be determined in several ways. Today, scientists identify 10 signs of a long life.
Long life has been granted to women by nature
Life expectancy is largely determined by sex: females of almost all mammalian species “outlive” males.
Scientists at the University of California at San Francisco, who for some time artificially raised rodents, found that among the long-living mice, the majority were those in which female sex glands were attached to the female chromosomes. The researchers concluded that hormones and other signaling molecules “live” in the ovaries of females, which prolong life and slow down the aging process.
Males are more vulnerable. The reason for this is testosterone, which easily damages the immune system. While estrogen (female sex hormone) has an anti-inflammatory effect.
Young appearance is indeed a good indicator
The younger a person looks, the more likely they are to become a long-liver.
Really youthful appearance also correlates with biological age.
For seven years, scientists have observed more than 1,800 pairs of twins and found that a twin who looked younger most often dies later than the sibling who was born earlier.
According to the researchers, the age that we perceive when looking at a person is inextricably linked with telomeres. We are talking about molecular biomarkers of aging, the shorter of which promise rapid aging of the body, the development of diseases, including cancer. People with a youthful appearance have elongated telomeres.
Vegetarianism is the ticket to a long life
According to scientists from Harvard, the largest number of centenarians who could be observed did not eat animal products.
Studies have confirmed the fact: when a large dose of proteins (especially those contained in meat and dairy products) enters the human body, cells begin to age rapidly. Since, together with protein, they receive a high-quality “building material” – they are tuned in to active growth and reproduction.
However, the adult body does not need such stimulation. Prolonged cell growth accelerates the aging process. If you reduce the amount of amino acids (reduce the proportion of protein in the diet), the cells will stop actively growing and will be able to devote all their strength to protecting the body. In this situation, the withering of a person will noticeably slow down.
Hemoglobin within normal limits – a clinical feature of a long-liver
A high concentration of iron in the blood accelerates the aging process in the body and, conversely, normal hemoglobin increases a person’s chances of living a long life.
Iron determines the ability of the human body to fight infection. So, for example, when diagnosed with Parkinson’s disease or liver pathologies, the hemoglobin level drops sharply or vice versa goes off scale. That is why British researchers suggested that the metabolism of this trace element is an important factor in the state of an aging organism and a tendency to longevity.

This fact is confirmed by alternative scientific work, the authors of which proved that excessive consumption of red meat – a source of iron – increases the risk of developing age-related pathologies, especially cardiovascular diseases. Researchers also did not confirm the exceptional benefits of iron supplements: after all, if you follow the logic, these medications can both help a person and harm him.
Healthy gut
Italian scientists studied the heroes of the day who were about to celebrate 100 years of life, and came to the conclusion: centenarians have healthy intestinal microflora.
People who live for a long time do not complain about the intestines, since they have a large number of beneficial bacteria in their bodies that “live” in this organ. They are engaged in the production of vitamins, the release of the necessary energy, the fight against infections, they also produce toxins on their own.
You can promote healthy bowel function by consuming foods with probiotics on a regular basis. The Mediterranean diet is another great way to improve your gut flora. It is this nutritional system that helps Italians live long. The diet of long-livers is dominated by seafood and fish, fresh vegetables and fruits – valuable sources of youth and vitality.
Doctors pin great hopes on the transplantation of donor material – intestinal contents with valuable bacteria. This technique has already found its application in medical practice, but at the moment the operation is performed not to prolong life, but as part of the therapeutic course of certain diseases.
Centenarians say no to excess weight
The risk of death in people with a body mass index (BMI) above 35 is increased by 29%, compared with those who are not overweight. This is exactly the result shown by a study conducted by American scientists.
Excess weight increases the likelihood of developing chronic diseases, especially diabetes and cardiovascular pathologies. Gerontologist Y. Konev confirms this fact. In his clinical practice, he also noticed a natural relationship between excess weight and a high risk of mortality.
In addition, the accumulation of fat around the waist practically doubles this risk, even if the BMI is normal. A sedentary lifestyle, unbalanced diet and, of course, genetics contribute to the accumulation of fat in the abdomen.
The earth loves the happy
American doctors have determined that a person’s life span is influenced by his worldview. They studied the life stories of thousands of men and women and found that more optimistic people live about 11-15 years longer than those who are used to falling into depression.
This is easy to explain, because cheerful, optimistic people rarely complain about the heart, lungs, stomach, etc. They often adhere to a healthy lifestyle – they monitor their diet, remain healthy, and get enough sleep.
Another trait of optimists that helps them live long is self-confidence. Such people are not inclined to panic, despair, they easily find a way out of even the most difficult situations in life and recover from stress much faster.
Activities for the benefit of physical and mental health
Centenarians are always on the move, because they and scientists around the world know that physical activity works better than other tools in the fight against aging processes in the body.

While a person is playing sports or just walking in the park, he absorbs a lot of oxygen. In the process of processing it, the body receives many free radicals, which tend to damage cells. It makes sense to assume that sports are just stress for the body. But take your time – since we are talking about short-term stress, cells are trained and strengthened in the process, which increases their resistance to the influence of negative factors, improves the ability to heal itself.
Physical activity really strengthens the body and prevents it from aging, however, this is only true for regular exercise. It is worth setting aside 40 minutes a day for a gym or a walk. You should not overdo it either, otherwise the reverse process will start.
The secret to longevity is in intelligence
Scientists have concluded that smart people live about 4 times longer than less educated people. It turns out that a brain that doesn’t take on a regular load ages quickly.
The level of intelligence also affects the state of human health. Boys with glasses get sick less and become profitable suitors, they are also preferred producers of offspring.
That is why today intellectuals are valued everywhere, they are lured from other countries. Smart people who live long and fruitful lives are the basic factor in the economic growth of a country and the well-being of the nation.
Loneliness is not a comrade of longevity
Scientists from England are sure that loneliness is a disease that “steals” years from a person. That is why they advise everyone who intends to live a long time to lead an active social life. This does not mean that there should always be a crowd of people around a person. Health will be strengthened by just a few strong bonds – with a husband, wife, children, other relatives or friends.
Studies show that individuals who prefer solitude are more likely to suffer from health problems. It is quite simple to trace the pattern here: being most of it alone, it is difficult to lead an active lifestyle, it is much easier to “pick up” a virus that the body simply cannot resist.
Becoming a socially oriented person is not as difficult as it seems. First of all, you should give preference to real communication with people, and not social networks. Daily communication with family about “how was the day” is also effective communication. The same goes for a seminal weekend in nature, a friendly meeting over a cup of coffee on Saturday.
These signs of longevity have a scientific basis. But the best part about this whole topic is that everyone can live long. Almost all the “traits” of centenarians can be developed in oneself.
If you feel that you are “behind” on any of the points, start working on yourself, devote time to your own health. After all, it is health that is somehow connected with all the listed points.
Take care of your body and mind and proudly join the ranks of centenarians. We have only one life – why not make it better and longer
