Looking back at my past work I believe I used to be more intelligent than I am now.
It feels like my brain is getting slower and slower.
A doctor told me this is a type of dementia associated with depression of which I have a history.
Sometimes I can just stare at an object for minutes at a time with nothing going on inside my head.
My question is whether there are ways to improve intellectual agility and to make your brain more nimble.
Maybe ask your GP if there are things like Notropil IIRC that might help you.
Learn a new thing, such as a language, stimulate yourself intellectually, such as learning whole new topics, such as molecular biology or colonial history etc.
