[T]hese clicks are so loud you can actually feel them in your body. Your body starts heating up after a few minutes. - James Nestor

[M]y doctor... told me, "A breathing class could help." ...strengthen my failing lungs, calm my frazzled mind, maybe give me perspective.

If you were to split a seashell in half and look at it, that's what's happening in your nose. ...[A]ll of this ...evolved for a reason... [A]ir that comes in through the nose is slowed down... filtered... humidified and it's conditioned, so by the time it gets to your lungs, your lungs can absorb that oxygen so much easier.

[T]he more you focus in on these clicks, the tinier... they get, [growing] into more complex structures. ...[O]ther ns such as dolphins and orcas also use these. It's this secret language... discrete codes... down to the millisecond.
