Reading and writing at any age can help keep your brain healthy later in life, according to a new study published in the journal Neurology.
Researchers found that the more active your mind is the better your memory and other brain functions are as you get older.
"By examining donated brain tissue this study has shed more light on this complex question, and the results lend weight to the theory that mental activity may provide a level of cognitive reserve, helping the brain resist some of the damage from diseases such as Alzheimer's," the Daily Mail quoted Dr. Simon Ridley, head of research at Alzheimer's Research UK.
They say activities like photography, writing letters or emails, or just figuring out daily problems can help.
"Our study suggests that exercising your brain by taking part in activities such as these across a person's lifetime, from childhood through old age, is important for brain health in old age," the study's lead author, Robert Wilson from Chicago's from Rush University Medical Centre, said.
