I just noticed you mentioned building more neurons - I thought I'd rea somewhere that the number of neurons was fixed at some point in teenagehood, and didn't increase beyond that? Or am I misunderstanding that point? (It would be pretty good if we could grow/regrow them).

It's generally accepted today that neurogenesis does occur in the adult brain. That said, probably the main activity in the adult brain is developing interconnections between existing neurons, which requires generation of new dendrites and axons and whatever other structures.
