If so, then your memory is unusually good. I know that this is well beyond my capabilities. Nor do I have the ability to visit a place that I lived 40 years earlier and find my way around.
I recently found myself in a hotel that I stayed in as a 7-8 year old in the 80s for a particularly memorable vacation with my extended family. It was funny that I still remembered the I unusual aspects of the layout and could spot many of the changes that had been made over the years.
But if you asked me to describe someone I met for a few days in a business context in 2020, I’d have a hard time remembering detail.
There also, AFAIK, isn’t evidence they remember _all_ other elephants they’ve shared time with for at least few weeks (I certainly do not rule that out, either, given the low number they likely will meet in their life)
Yeah? Maybe not if they were a kid 20 years ago or their appearance had otherwise changed significantly, but otherwise I don't see why not.
