As the body does not regenerate neurons and nerve cells, does that technically mean that every brain cell we have are with us for the entire duration of our lives? I can never get my head around this.

We can make new neurons but they are pretty.. unmapped?..so for the most part we lose them slowly.
Yes we do keep the same neurons iirc but our brain has quite the elaborate cleaning system and prunes neurons and paths to be more efficient… like the gleial cells around neurons we often thought..well as the name implies just to be more or less glue … turns out no they are quite the elaborate cleaning system and they serve more functions
More neurons doesnt necissarily mean less smart. It can also mean more efficient function
