Re Adrian Chiles (The left lane on a motorway is for the virtuous and the good. That’s why I love it, 2 November), I agree and am the same species of nerd. Early in my now 60 years of driving, however, I was strongly advised by some older know-it-all that, on the growing number of three-lane motorways, “the inside lane is for lorries, the middle lane is for cars and the outside lane is for salesmen”.

• I have personal confirmation that my brain health declined from 2019 to 2020 (Covid pandemic ‘had lasting impact’ on brain health of people aged 50 or over, 1 November). In 2020 you printed 12 of my letters, but in 2020 it had declined to six. However, I received a step counter for Christmas in 2020 which seems to have perked me up, as you published 13 in 2021.
