I was hoping there would be a constructive comment about the similarities and differences between помнию and вспоминаю. At the time that I had reached this point to study these, along with a bunch of other verbs, was when Duo changed their system (and disallowed people from repeating the "same lesson" over and over and over until things stuck) and at that point my study routine went pear shaped. Any chance that someone could help out a slow learner please?
This is physically impossible, because there's only so much information your brain can hold, and a fraction out of that is set aside for remembering things. Then, to make room for new memories, your brain has to push out old ones. So in order for you to remember everything, then you'd have to have an extremely large brain capacity that wouldn't fit your skull.
So much for remembering everything.
