Now I think that there is a popular model of how to do this and as we look at some of the titles of the popular literature that are out there I think you will get a sense of this. The popular model of preserving cognition as people age seems to be this: I will increase my cognitive activity in everyday life, or through something, and that will improve my everyday function and it will slow my cognitive decline – maybe it will even prevent me from getting Alzheimer’s disease. And how will those two things occur? It will occur because I’ll have changes in the cerebral organization or the function of my brain or thinking. And when I meet older people, and as part of my job I meet a lot of older people, who feel threatened or legitimately have had changes in cognition, this is exactly the model that their families especially and often times their self espouse. And I am beginning to see this in the popular literature. So I’m not proposing that this is a model for what is happening but I’m remarking that this seems to be what people are thinking about.
