Older people do not decline mentally with age, it just takes them longer to recall facts because they have more information in their brains, scientists believe.
Much like a computer struggles as the hard drive gets full up, so to do humans take longer to access information, it has been suggested.

“The brains of older people do not get weak. On the contrary, they simply know more.”
