Reading daily could help keep your brain in shape as you reach old age. Research suggests that reading books, writing and participating in brain-stimulating activities at any age may preserve memory.
One study found those who engaged in mentally stimulating activities (such as reading) experienced slower memory decline compared to those who didn't. In particular, people who exercised their minds later in life had a 32 percent lower rate of mental decline compared to their peers with average mental activity.
The study’s author, Robert S. Wilson, Ph.D. of the Rush University Medical Center in Chicago, said: "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. Based on this, we shouldn't underestimate the effects of everyday activities, such as reading and writing, on our children, ourselves and our parents or grandparents."

Speaking of Einstein, I'm reading a book about anti-gravity. It's impossible to put down.
