Neuroplasticity and prevention from aging with CW

In the mailing list of FOC, Dave VE9CB has recently made a post regarding prevention from dementia with CW operation. It is a short introduction of a paper written by W4DNN, which I tried to link or paste here without success. The paper by W4DNN says training CW will bring forth neuroplasticity which may mean to prevent from aging and/or dementia. The original article W4DNN mentioned was also introduced here by myself; http://nuttycellist-unknown.blogspot.com/2017/10/learning-morse-code-results-in.html

Learning Morse Code is comparable to learning foreign languages, as the paper says. It takes too long to observe neuroscientific findings associated with learning foreign languages and observing it with learning Morse Code could be a replacement for that study. Morse Code may survive as a subject/study tool in that field in neuroscientific research. Morse Code is composed of simplest symbols as you know, which is advantageous in such research in scientific epistemology.

The important difference between learning foreign languages and Morse Code is that Morse Code could not be a language due to no grammar in itself. Morse Code is only a system of symbols corresponding to each letter, numerical letter or symbol. If CW communication should be claimed to be comparable to a language, it should convey some sort of meaning in the message and should be constructed with the grammar of certain language the communication is made with. Without meaningfullness in CW communication based on certain language, it won't be associated with neuroplasticity.

Thus meaningfulness in CW conversation is still of primary importance if it should be compared to learning foreign languages which could stimulate our intelligence and may prevent us from dementia.
