Greetings.
A certain question with possible nootropic implications has been plaguing me, and I thought perhaps someone else out there may have had similar thoughts. Let me explain my situation:
I'm 30 years old, and my current goal is make a return to academia in order to finally earn the PhD I've always wanted. However, I've begun to notice subtle changes in my cognition since, say, 5-7 years ago. I certainly don't feel that my mental capacities have diminished, but my find somehow feels less "flexible". For example, learning languages seems a bit more difficult. I fear that certain modes of thought which I've deveopled over the past years are becoming "set."
In order for me to achieve my goal, I feel that it is very important I do whatever I can to maintain a youthful, flexible mind. "Spongy," if you will. Like a sponge, ready to absorb new information, adopt new modalities, etc.
Does anyone know of anyway to slow or reverse this trend? Doesn't have to be nootropic; could be meditation? entrainment? games? creative writing?
