I have been a postdoc for many years now in a theoretical field. Thus, while progress in my career has been slow, I am not without experience. There is one particular thing that I feel keeps limiting me, and has been a source of a lot of anxiety and worry: over just a few months, I forget things I learned. I forget the names of techniques, theorems, authors about which I had tens of conversations. I forget mathematical techniques and derivations I worked with many times. I forget how to effectively use programming languages I have not used for as little as 6 months. I forget small theoretical results of proofs I produced and neglected to write down because they seemed trivial t the time.
I worry that personally I am much worse at remembering than others, and sometimes this makes me wonder if an academic career is even suitable for me. There are people I admire for their vast knowledge and how they can contribute something meaningful and relevant to just about any conversation. I wish I could be like them, but all I can recall is some very vague memories, unless I am currently working with the topic we are discussing.
Are other people struggling with this issue too, and are there techniques or exercises to improve? Is this perhaps caused by the constant flood of information that bombards us in this digital life we lead, and maybe displaces the actually useful knowledge we accumulated earlier?
I apologize if this is considered off-topic. Just delete the question then. This is something that has been seriously worrying me for years now, and it is hard to discuss face-to-face.
