I suspect that I caught covid a few months ago and noticed a little difference in my oratory and reasoning, confusing some basic words, and it seems that the sound of my internal voice with which I speak has decreased, however for a short time, and yes, exercise helps a lot. it took me eight months or nine to recover, not completely, but it looks 95% like I was before, well in my case it took a little bit of effort, it's like a temporary mental fog, now I'm better, so i hope you get better too. and i agree with you, the only person that can take care of yourself is yourself, it's your own life, not someone else.
I don't think you rambled; everything you said was purposeful. Sounds like a plan. Looking forward to more videos - I cannot imagine the energy it takes to do them! Glad you're on the mend!
