Scientists at Northwestern University in the United States have discovered the type of people who manage to stay young for decades. It's all about a special characteristic of the brain, due to which such persons receive the potential for rejuvenation.
The researchers conducted an experiment in which 62 people took part. The subjects were over 80 years old, and they considered their memory good. During the study, scientists identified 15 people whose mental abilities were no worse than 55-year-olds. At the same time, these participants in the experiment had completely different IQ, lifestyle, educational level.
The doctors concluded that the excellent memory of the volunteers is due to the size of their brains. Elderly subjects who showed good cognitive ability underwent MRI with an interval of 18 months. At the same time, 15 people underwent the same examination, whose memory is not surprising.
It turned out that the volunteers from the first group had a larger brain volume, which decreased at a slower rate than usually occurs in people of this age. Scientists say that the surveyed volunteers in their youth and middle age did not show such impressive results; they began to demonstrate such abilities only after 80 years.
