Communication with young people prolongs the life of even flies
Communication between the old and the young prolongs the life of the former, and this applies not only to human society, but also to animal communities. Hongyu Ruan and Chunfang Wu from the University of the American State of Iowa did not limit themselves to psychology and developed a biological model to study the molecular mechanisms of this phenomenon. The work of the scientists is published in the Proceedings of the National Academy of Sciences.
Scientists have worked with fruit flies with artificially shortened life expectancy due to numerous mutations simulating age-related diseases of people – Parkinson's, Alzheimer's and Huntington's disease. Flies grown together with other "sick" lived twice as much as mutants genetically identical, but grown in a chamber with "healthy" fruit flies.
Scientists have not yet established the mechanism of such a phenomenon. Perhaps a convenient model will help to do this in the near future, although the fact that care is the best supplement in the treatment of age–related diseases is understandable even without knowledge of the mechanisms.
