With Father's Day coming fast, you may need more ammunition just to remind your kids that your brain works just as well as theirs do, and, even better in some cases. When that time comes -- and you know it will either tomorrow or down the road -- don't forget this study or to send a few kind thoughts my way for telling you about it.

Duke University researchers worked with two groups of adults (ages 18-35 and 66-76) to measure the differences and commonalities in the way both process new information and make risky decisions based on losing or gaining real money. You may or may not be surprised to learn that the assumption made about most older folks -- they make bad decisions because they're too gun-shy and risk-adverse -- is generally wrong.

Using path analysis to measure whether age had anything to do making good decisions, scientists determined "the numbers game" did have an effect on the processing speed and memory. Just not on the quality of the decisions patients made…

And, some older patients made better decisions than younger ones who had lower scores on cognitive tests. "If I took 20 younger adults and 20 older adults, all of whom were above average on these measures, then on average, you could not tell them apart based on decisions. On the whole, it is true, more older people process slowly and have poorer memory. But there are also older people who do as well as younger people," says lead researcher Dr. David Huettel.

You can bet, the next time I have an argument with one of my kids or extended family about making the right decision about anything, I'll send them a link to this blog post in nothing flat!
