IQ and dementia

not only do people with lower IQs die earlier, they also may be at greater risk for dementia.

if the correlation between IQ and life satisfaction is still statistically insignificant after factoring in attrition, it would illustrate an important point. although one may be no happier or satisfied with a higher IQ, this trait may lend other important benefits impacting well-being aside from satisfaction with life. IQ may be just like wealth, in that sense, providing a type of insurance against later dissatisfaction or unhappiness, although not impacting it directly.
