Regardless of age, you're unlikely to have a flawless memory. People who can remember very long lists of numbers or recall the minutiae of their daily lives — right down to what they ate for lunch every day last year—are exceedingly rare. And frankly, such a memory can be a burden rather than a blessing. Memory, it seems, is inherently flawed—and in more ways than you might think.

Daniel Schacter, a professor of psychology at Harvard University, described the most common ways that normal memory fails us in his book The Seven Sins of Memory. Some of these memory flaws become more pronounced with age, but unless they are extreme and persistent, they are not considered indicators of Alzheimer's or other memory-impairing illnesses. They are simply the way that our brains work. The following is a brief summary of two of Schacter's seven memory "sins."

Your daily habits and lifestyle — what you eat and drink, whether you exercise, how stressed you are, and more — affect your mental health every bit as much as your physical health. A growing body of research indicates that regular exercise and a healthful diet can help protect your memory from aging-related decline.

Exercise

Physical fitness and mental fitness go together. People who exercise regularly tend to stay mentally sharp into their 70s, 80s, and beyond. Although the precise "dose" of exercise isn't known, research suggests that the exercise should be moderate to vigorous and regular. Examples of moderate exercise include brisk walking, stationary bicycling, water aerobics, and competitive table tennis. Vigorous activities include jogging, high-impact aerobic dancing, square dancing, and tennis.

You've probably heard about tests to measure chemicals in the blood that indicate chronic inflammation in the body. They are sometimes used to estimate risk for heart disease. But what about using these kinds of biomarkers to gauge your risk for declining brain health? A study published Nov. 1, 2017, in Neurology found that having certain inflammatory markers in midlife was associated with brain shrinkage and poor memory in older age.

Researchers measured five inflammation biomarkers in about 1,600 middle-aged people and gave them brain scans and a memory test about 25 years later. Compared with people with no elevated inflammation markers, people with high levels of three or more biomarkers scored lower on the memory test and had about 5% shrinkage in the hippocampus and other parts of the brain associated with Alzheimer's disease.

Feeling afraid about life issues is common as you age, but if it takes over your life, you may have generalized anxiety disorder (GAD).

Everyone feels afraid or worried at times, but if these feelings begin to take over your life, then you may have crossed over into generalized anxiety disorder (GAD), which is the most common anxiety disorder among older adults, according to the Anxiety and Depression Association of America (ADAA).

"The issue with many older men is they often just endure the discomfort of GAD, or think it's normal, and do not talk about the problem," says Dr. David Mischoulon, director of the Depression Clinical and Research Program at -Harvard-affiliated Massachusetts General Hospital. "However, left alone to manifest, GAD may lead to serious health problems, such as high blood pressure, depression, and addictive behavior like excessive drinking."
