Why is longevity related to heredity?
People with long-lived parents generally have long-lived children, and longevity seems to run in the family. Slag Boom, a researcher at Leiden University in the Netherlands who studies the relationship between longevity and heredity, said:
"People who live longer do not have fewer cancer genes or aging genes. In fact, they have other genes that can stop the disease genes from attacking. A large part of longevity is still related to genes and heredity. " Their research report shows that the physiological functions of long-lived family members are slightly different from those of ordinary people.
German scientists investigated 576 centenarians in 15 years, and found that the average age of their parents when they died was 9- 10 years older than the average person.
A slight mutation in a special gene combination can obviously prolong a person's life. Scientists discovered the genome of methuselah in their research. According to the British Times, it seems that the genome of methuselah can protect people from smoking and bad eating habits, and can delay the onset of cancer and heart disease.
Of course, although genes play a very important role in longevity, they are not the only factors that determine longevity. Environment and living habits also play an irreplaceable role in longevity.
