If you like to breathe don’t be self-conscious about it. The best medical opinion states definitely that breathing is not only normal – it’s healthy. This has to be qualified, of course. Breathing water, illuminating gas, carbon monoxide, etc., is not healthy at all. Breathing air is what we’re talking about – breathing enough air that contains enough oxygen. Let’s first take a look at the broad principle behind the relation of air and oxygen. There are a lot of misconceptions with regard to breathing and air and we’ll do well to knock them in the head right away.

Hold on to your oxygen masks, men, we’re going to tell you.
