> If I hear something once, I understand it and remember it for life
Must be nice to have that kind of recall at the age of 100.
That being said, some people (John Von Neumann) seem to have had fantastic visual and textual recall.
A number of artists (Kim Jung Gi) and musicians (Mozart) seem to have developed remarkable visual and auditory memories.
And many children or fans who were nothing special in school can easily name every Pokémon, or tell you the stats and history of every member of a sports league, or recite the Star Wars saga line for line.
(And chickens, flightless though they may be, still possess the spatial brain of a migratory bird and can memorize (and peck) 300 random locations in their cage space - or on a piano - in order. They're also much better than rats (or humans?) at mazes.)
