A younger human appearance has been the focus of many scientific disciplines for centuries. From a medical point of view, appearance is not only an indication of a person's age, but also a picture of our body's health and well-being. Scientists in the Netherlands, in the course of gene research, have discovered the gene responsible for our younger appearance, regardless of the age we are - MCIR. People whose genotype is equipped with this gene were judged to be at least two years younger than the metric would indicate.
