Help to understand parts in this video

Hi, this is a nice new video I try to understand, it only looks long, but the unclear words are not much… thanks for your help ??

At 1:17 the bird is a spirit __2 words___ and so

At 1:41 just how _1 word_____ it is to learn

At 1:52 There's no learning in that and that's happy it's

Subtitles show "happy", it seems strange…

At 1:58 and maybe ________ hard

What is the expression there?

At 2:00 and then you down into the depths you go,

This phrase as a whole end on "you go"? I ask that because I don't know if maybe I have here two different phrases; one is "and then you down into the depths. And the second one is "you go"… when coming to understand it, it's might get confusing ??

At 2:22 into flames, bang ____ new you

Does he says "egg"?

At 2:37 like grizzly bears is now

I'm not sure if he says "is"? maybe it's other word there?

At 3:05 and it's ____ you have to eat a lot

I think it's "costly" (it refers to childbirth…)

At 3:13 but the advantage is your __1 unclear word_____ you can learn

At 3:38 or a deep habit really built into you

Here again, I can't tell if this is one "unit" of sentence, or that it two different sentences; "or a deep habit". "really built into you".

At 3:42 it's a neural structure, right? it's a ____ and

He says lie?

At 4:48 drunk friends and _1 word___ maybe you've had them for your whole life

At 4:58 with that 20 hours, it's like hanging around your neck like an __1 word?___ and so

I hope I got this sentence correct??
