When you reach a certain age, every lost key or hard-to-conjure word comes with a nagging question, is my mind slipping? The answer, unfortunately, is probably yes, but that doesn’t mean that you’re becoming senile or have something to worry about. Most people experience a little bit of forgetfulness as they get older, particularly in their 60s and 70s, and this is the result of subtle changes in processing speed that begin in your 20s. 

Initially, these changes are too small to perceive, but eventually, they become noticeable. Growing older does not mean that your mental abilities will necessarily be reduced. There’s a lot you can do to keep your mind sharp and alert. Researchers believe that many of the supposed age-related changes that affect the mind, such as memory loss, are lifestyle-related. Just as muscles get flabby from sitting around and doing nothing, so does the brain.
