Brain health depends on several factors.
According to Christina Dalla, a professor at the National and Kapodistrian University of Athens, regular exercise, a healthy diet, an active social life, and creative activities can all help keep the brain in good condition.
She also explains that learning activities requiring mental effort can strengthen the brain, according to HealthDay.

They then tested the model on 144 people with varying language proficiency.
The study was presented at the Federation of European Neuroscience Societies (FENS) Forum in Barcelona but has not yet been published in a peer-reviewed scientific journal.
The researchers now plan to investigate whether language skills may also influence diseases such as Alzheimer's.
