Something else I have noticed is I find it harder to spot spelling mistakes. In the past spelling mistakes were obvious: words just shouted out as wrong, but these days I find I struggle more to even realise the spelling is wrong. Sometimes it is my keyboard but more often it is my inability to spot the error. This is I'm sure an after-effect of my cerebellum brain bleed and not old age.
Also, I tend to forget some things. I may have posted something along these lines before! If so, you may have read this already in the last few months - please accept my apologies. Thankfully, my intellect is still sharp.
