Just a couple of mutations in genes can dramatically shorten the lifespan, established professionals from the University of Edinburgh. It is interesting and different. These damaged genes are present in the body 70% of people.
For the experiment, researchers took data on the human genome 150 thousand people. Analysis of mutations showed that the absence of changes in the genes APOE and CHRNA provides extra 4 years of life. However, mutations in these structures, according to the study, occur in two of the three people in the UK.
Genetic factors have a major impact on human health and lifespan. According to experts in the field of medicine, the genes responsible for approximately 20% of health. The greatest role is played by the lifestyle and level of wealth. Forget about it not worth it.
