You are quite as capable of learning now as you ever were. You just have to budget more time. Not because you got worse at learning, but because you already know so much. Whenever you learn something new, your brain has to reconcile it with what you already learned (or mislearned!). You have to undo more of the prejudices you've picked up, you have to resolve the cognative dissonance which comes from realizing that you've been wrong. Sometimes this causes profound crisis, as when changing/losing religion, or allegiance to political party or economic system. You have been warned :-) But if you want it, you can learn it. It is yours for the taking.
