A Wordle habit probably wouldn’t protect Emma Brockes from dementia (My five-letter reaction to the New York Times taking over Wordle? I quit, 17 February). There is a myth about puzzles and brain health. The human brain is large because we are social beings. Meeting our fellow creatures is more likely to keep us well. The Lancet’s review, published in 2020, is useful for those interested in what makes a difference – eg exercise, eating well, voting for clean-air policies and embracing education. If your family tells you that your hearing is getting worse, get it checked. Gather with others in whatever way you can. If you like peace, quiet and indeed word puzzles, enjoy them in moderation.

• In response to Emma Brockes and other adopters of Wordle, I have one word: crosswords. Never knowingly bettered.
