A new study suggests that mental activity may help delay the onset of Alzheimer’s disease (Busy Minds May Slow Alzheimer’s).

According to the Law of 5 elements, mental activity belongs to the Fire element, which is exactly what the mind needs to stay healthy. Mental activity, done in moderation, thus helps delay Alzheimer’s disease. Mental over-exertion, on the other hand, would deplete the Fire element and worsen the problem.

Since the heart and mind are related, according to the Law of 5 elements, the above also affects the heart: mental activity helps keep the heart healthy but overdoing it is likely to weaken it.
