The first best habit to prevent memory loss is exercise. When we say exercise, we need to be a little more specific and say that it only counts if it's moderate exercise. To clarify,
you have to feel out of breath, and it should be relatively hard to hold a conversation while you are doing whatever activity you enjoy.
You should eat a diet low in carbohydrates. What that means is you eat less rice, pasta, white potatoes, white bread, things that your body absorbs very quickly
The third best habit is to look at how much time you spend with other people and make sure you have strong social connections.
The fourth best habit is to always be learning something new. This could take the form of finding a new hobby to develop,learning how to make something or build something.
Another good habit to always have is taking safety precautions when doing activities. Specifically, we are trying to prevent head injuries.
Finally, the best habit is to check in with your doctor regularly, and if you are over the age of 50 that means at least once a year.
Please focus on one thing at a time, do not try to make many changes all at once because habits form best when they happen one at a time.
Take some notes & you can check on many of these things at your next doctor's visit. Also, ask your friends & family for advice because sometimes people who know you well will have good ideas for you
