What happens to our brains as we age is of crucial importance not just to science but to public policy. By 2030, for example, 72 million people in the US will be over 65, double the figure in 2000 and their average life expectancy will likely have edged above 20 years. However, this demographic time-bomb would be much less threatening if the elderly were looked upon as intelligent contributors to society rather than as dependants in long-term decline.

A.he idea that we get dumber as we grow older is just a myth, according to brain research that will encourage anyone old enough to know better.
B.Using computer models to simulate young and old brains, Ramscar and his colleagues found they could account for the decline in test scores simply by factoring in experience
C.It is time we rethink what we mean by the aging mind before our false assumptions result in decisions and policies that marginalize the old or waste precious public resources to remediate problems that do not exist.
D.Many of the assumptions scientists currently make about ‘cognitive decline’ are seriously flawed and, for the most part, formally invalid.
