Older people who have low expectations of a satisfactory future tend to live longer and suffer fewer disabilities than those who are overly optimistic, according to a study based on data from 40,000 individuals between the ages of 18 and 96.

As we age, it becomes more expensive for us to learn languages, memorize data ... A study by the Medical College of Georgia (USA) suggests that it is because the brain loses the ability to filter only what is relevant and to eliminate old and obsolete, rather than difficulties in storing new material.

Brain aging slows down due to the absence of DNA polymerase?, Known as the Pol gene ,? according to an investigation in which the Higher Council for Scientific Research (CSIC) has participated and published in the journal PLoS ONE. The results suggest the ability to learn and remember at advanced ages in mice is related to the activity of this gene and cell repair.

A genetic variant associated with an active, sociable and audacious personality increases life expectancy, as researchers at the University of California at Irvine (USA) have just shown in a study published in The Journal of Neuroscience.

In the course of 2012, the work of scientists in Spain gave headlines, opened news reports and featured on the covers of the best scientific journals, as highlighted by the SINC agency in its selection of the most outstanding research in science "made in Spain" .

The tendency of the mind to wander is related to aging, according to a study from the University of California. Telomere length, a marker that has proven useful in measuring cellular aging, appears to be associated with a tendency to let the mind wander to thoughts about the past and the future, or simply "to be elsewhere." . Specifically, people who wander the most have shorter telomeres, which means that aging is accelerated.

Although it may seem like science fiction, it is not. According to a study published in the 'Journal of the International Neuropsychological Society' and conducted by experts from Northwestern University, there is a select group of people over eighty years of age, known as the "SuperAgers" or "superannians", who have an anatomy special brain that allows them to think and remember even better than people twenty or thirty years younger.

Scientists from the University of Florida (USA) and Shanghai Fudan University (China) have shown that adults who practice Tai Chi three times a week have greater brain volume and better results in memory and reasoning tests. The results are published in the 'Journal of Alzheimer's Disease'.
