...family income of military recruits with the income of all American families. They estimated that the mean income of military recruits was $41,141, almost the same as the national average of $41,994. But families with 18-24 year old children tend to have parents in their peak earning years. Comparing recruits to all families—including young families with low incomes and low expenses and old families with lower incomes and lower expenses—makes military recruits seem middle class. If we compare them with families headed by individuals in their 40s, the picture looks different...

It started out protean, gained shape and intellectual muscle as it matured, and reached its peak of power and nimbleness by age 40. After that, the brain began a slow decline, clouding up little by little until, by age 60 or 70, it had lost much of its ability to retain new information and was fumbling with what it had. But that was all right because late-life crankiness had by then...
...years old as well as in hundreds of older people suffering from such brain-related ills as Alzheimer's and Parkinson's diseases. As he suspected, the healthy adults had the most myelin in the frontal and temporal lobes--where big thoughts live. The quantity of sheathing reached its peak around 45 or 50, exceeding the amount in unhealthy older subjects and healthy younger ones...
...inductive reasoning occurred from their 40s to their early 60s. Similarly, their so-called affect optimization (the ability to highlight the better aspects of one's personality and restrain the less attractive ones) and their affect complexity (the ability to evaluate various contradictory ideas and remain objective) did not peak until their 50s or 60s. There was also an increased tolerance for ambiguity and an improved ability to manage relationships...
