“There are studies showing that, for example, it is really hard to get dementia when you are a university professor, and the reason is not that these people are smarter – it’s that until old age, they are habitually engaged in tasks that are very mentally demanding.”

That’s an interesting point. I wonder if that applies to any knowledge work in general. As a developer I do feel that I engage my memory pretty often but I’m not sure it counts as a wholistic exercise including spatial memory, recalling events, reasoning, etc.
