Now, it may not apply to me or anything, but I'm sure you know that I just can't help but to apply my knowledge if there's a place for it. You mentioned in that critique that with really sensitive hearing, you could hear the inside of your own ear. Technically true, but it wouldn't matter. The brain blocks out constants, it's why you can't see your own nose, or constantly smell yourself. You can already hear your own blood with your normal hearing (it's right next to it, after all), it's just that your brain ignores it. Really interesting, the brain is. 

Anyway, no other comment on anything. I just couldn't help but to say that.
