How to breath the right way and why do I feel my chest?

You made this thread yesterday, so I'll say the same thing.

Your body regulates it's oxygen intake whether you're consciously breathing or not.

Normal number of breaths is 12-20 a minute. Anything outside that range is strenuous, involuntary, and you'd be able to tell you're in peril.

So basically if you're not cyanotic, you're fine.

Breathe with your chest and shoulders, but your stomach, if you don't already.

Where do you expect the air to go when you breathe in?
