Q. Is it true that people who retire early experience a drop in their mental ability?

 A. A study by the National Institute of Health for the USA reported that: “Early retirement has a significant negative impact on the cognitive ability of people in their early 60s that is both quantitatively important and causal.” There is a trend in some countries for people to retire even earlier than age 60. In other countries, there is a trend for individuals to work well past age 65 if their current job allows for that and, if not, individuals may find other employment at least part time. Challenging mental stimulation is very important to retain brain function. Those who retire from jobs that are mentally challenging and do not obtain replacement mental stimulation may be at higher risk. Remember to factor in the understanding that every brain is different, and every person has a different health profile. Starting as early in life as possible to create and live a longevity lifestyle is likely the best option.
