Beware you young men with fresh brains. Brains can and do get worn. I could say almost exactly your words about my younger self, but not anymore. Now I suffer badly from never having learned and trained a good note system. Get your external memory configured and operational in due time.

What age did you notice it change?

[jonsen]

In my late forties. The quality of my lectures became fluctuating. Thought it was temporary but soon realized that on average it was slowly but steady downhill. Edit: Should say, that’s twenty years ago and not the slightest indication of dementia today. But significantly harder to handle complex things in my mind only.
