Assuming you are running on well-maintained hardware (your brain), I don't think there's any set limitation to how well your intellect will function after a long period of time.
We forget. A lot. As a normal course of thinking. And that's OK.
Old habits (good and bad) do die, with a bit of effort, if they aren't being constantly reinforced. If you make it a point to continually refine and improve how you think (trying to disabuse yourself of invalid ideas), then you are setting yourself up for a better future.
