Research by British scientists involved in the problem of brain aging has led to alarming results: it turns out that the aging process has been launched by the age of 45.
The study, conducted over a decade, was attended by 7 thousand people 45-80 years old. The participants in the experiment regularly passed various tests that evaluated vocabulary, memory, and speech perception.
The results showed that intellectual abilities are significantly reduced already by the age of 45 - by 3.6%. With increasing age, this figure is rapidly progressing. So the mental abilities of men after sixty years are reduced by 9.6%, for women - by 7.4%.
