I agree.. and have agreed about all these things becayuse I believe the narrative promoted by the medical industry, what else do we have ..?.. I do all those things you mentioned , most if not every day.. however both hubs and I work in the media/entertainment industry, and we've known friends.. jorunalists /actors/ political heads, and authors all who have succumbed to this horrendous set of diseases kknown under the Umbrella of dementia
None of these people, and I can off the cuff think immediately of at least 12.. were couch potatoes. All were active in their person and professional lives.People who for example had to learn 50 pages of script every night... ( that certainly keeps the brain cells well oiled, you would presume)..actors who sat between takes every day doing the Times crosswords.. writing their own memoirs playing suduku puzzles or chess.. ..
Famous authors
It puzzles me very much , everytime a friend or colleague falls prey to Dementia.. when I know they've done evrything they potentially could to keep their minds healthy.. and still become a victim..
As Dementia is just an umbrella term for a whole set of mental health infirmities..such as Alzheimers.. and many , many more.. it can't be possible to know how to ward them all off.. and from my point of view.. although making the brain work with puzzles etc, might be useful in the short term .. I really can't see ( at least from watching my own friends and colleagues)>. that it makes any difference in staving off certain dementias...in particular Lewy Body dementia, and Alzheimer's..
..and also not forgetting that altho' rare Demntia is also attacking the young!!
