Our brains really do shrink as they age. But new research finds that regularly engaging in reading, swimming, gardening, or other activities could slow the process.
When it comes to protecting your brain, physical activity is key. Your diet also plays a major role in this, try to eat healthy foods and don't be afraid of healthy fats (like Omega-3), get enough sleep, get some sun exposure as vitamin D is also linked to excess shrinkage, make a habit of reading as your brain needs you to read every day, and also try to engage yourselves in some mind focus exercises.
While all these answers are legitimate, it is possible that the ingestion of chemicals may be causing the extraordinary rise in alzeimers and other brain diseases. There is a correlation between their general introduction and the age groups badly affected, not reasonably explained by age alone.
Not all brain shrinkage is preventable, but such research suggests that finding ways to control your blood pressure may help. Regular exercise and eating a balanced diet are two things that may help you control your blood pressure. Research suggests that in addition to exercise, other protective factors such as a healthy diet, challenging leisure activities, socializing with others, avoiding smoking, and limiting alcohol intake can also reduce age-related brain declines.

Causes of brain shrinkage are closely related to symptoms of aging, including cardiovascular disease, obesity, diabetes, and even poor sleep habits and distress.
You may be able to prevent brain shrinkage by adopting healthy lifestyle habits and using supplements that target your own aging body’s vulnerabilities.
Supplements that reduce your cardiovascular risk, lower your blood sugar, or improve your sleep, for example, may do double duty in slowing or stopping brain shrinkage and improving your chances for a long, mentally fit life.

Aerobic exercise, reading, activity that involves problem solving (BJJ) and reactive component and vision (tennis), memory tasks - trivia etc. One of the main components of an aging brain is slower processing and being distracted easily .
The 1 hr morning walk, up and down the slopes, taking fresh air and enjoying nature is just exciting. Reading is also helpful as well as determination to create one's personal environment of joy, no matter the the situation, is the best.
