Is perfect pitch really that impossible to learn for oldies?

[Elom0]

Around february I'll be 24 years alive since germination. Apparently beyond 9 years alive developing perfect pitch is not possible for most, although recent studied seem to have put this in doubt.

For learning perfect pitch this is the best one I've found so far

This one doesn't seem--or should I say sound--so good

The second doesn't seem so good because randomly hearing notes sounds like the opposite of what it takes to learn perfect pitch. You have to develop 12 strong emotional connections, one with every note, and perfectpitch.training seems to do this more. The tonedear site seems like how someone who has doesn't properly understand how perfect pitch works would think of training.

Anyhow, in this brain state I am in now I'd need to use more consious mental connecting to learn perfect pitch, but when I'm thinking like myself I don't see how it would be difficult at all. When I heard a Zen Buddist chant when I was feeling emotionally low at that point my mind made a strong connection with note the chant was in throughout, which I later found was the Key F. So even in this brain state I am in there is a way for me to learn perfect pitch, yet alone when I am thinking normally.

And of course all this is likely very relevant to learning go too . . !
