A neuropsychologist established a reading norm that will slow down the aging of the brain": reading at least one page of a book a day saves you from dementia. "For older people, reading is necessary, even just a page, to maintain brain tone, as well as to delay age-related changes - dementia and the like. It is no longer so much for culture but for the health of cognitive functions. Middle-aged adults usually do not read so much, because they are actively engaged professionally, but they also need to maintain a good state of memory, attention, thinking and speaking. Literary works, and not just professional literature, are very important for this. At least a page, but preferably."
