To a greater extent, life expectancy depends on the environment.
An international group of geneticists has established that the life expectancy of a person depends more on the environment than on genes. These scientists have found out, finding out how the epigenetic regulation of the genome of twins changes with age.
It is reported that DNA methylation is one of the factors of human aging, in which the DNA molecule is modified without changing the nucleotide sequence.
Specialists have established that with age, the pattern of methylation of the genome varies. Previously, it was assumed that the picture directly depends on the genes, but scientists have proven that the greatest impact is the environment.
Scientists also stressed that life expectancy can be significantly increased if you consume healthy food and exercise.
