Wow. So many opinions, so few facts. There was an interesting set of articles in a special edition of Discover magazine that was put out a little over a year ago, called "The Brain". It states that grey matter "may begin to dwindle in our twenties, but for most of us crystallized intelligence - reasoning based on a lifetime of knowledge, skill, and experience - remains robust into our early sixties." Further, it goes on to say that "barring severe disease, we are capable of learning and forging new nerve connections throughout our life. Some areas of the brain continue to produce new neurons into our eighth decade and probably beyond. Designed with a redundancy of neurons and connections, the brain can rebound from damage and compensate for the loss of circuites with age. One example of its adabability: The older brain uses both hemispheres to tackle tasks that, in younger brains, are processed using predominantly one side." The article on the "elderly" brain states "research has revealed a few upsides to getting older: Better judgement and a more positive attitude turn out to be normal parts of the aging process." Also in this same set of articles is the suggestion by researchers that while we may lose grey matter as we age, the circuitry becomes more efficient. And they say that decision making is far superior in the older brain than the younger brain. So yes, there seems to be an upside.
