The brains of older people only appear to slow down because they have so much information to compute, much like a full-up hard drive, scientists believe.

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. Researchers say this slowing down it is not the same as cognitive decline. ´The human brain works slower in old age,¡ said Dr. Michael Ramscar, ´but only because we have stored more information over time. ´The brains of older people do not get weak. On the contrary, they simply know more.”
