Scientists have named five signs that a person will live a long life.
It mostly depends on genes, but lifestyle also plays a role.
What makes potential long-livers stand out?
According to research, life expectancy is highly dependent on gender: women, on average, live longer than men.
Scientists also discovered that there are as many as four longevity genes.
In addition, studies have shown that genes responsible for iron metabolism are associated with life expectancy, and that high levels of this element in the body shorten life. Therefore, it is not worth overindulging in red meat.
Scientists believe that taking iron-regulating drugs can add several years to life.
The level of education is also important, or more precisely the genetic predisposition to it. Research has shown that the higher the polygenic score (a set of genetic variants that determine the desire for knowledge), the longer a person lives.
A person's worldview also plays a role: optimists, according to research, live longer than pessimists.
