A note on breathing

I understand the value of breath, there is the obvious fact that it keeps you alive, but there is also a lot of value in using breath to calm you down, center your mind, work you through some more difficult situations, etc. And for the most part I completely take my breath for granted. I even took it for granted during the 1/2 marathon. I certainly wouldn't have been able to make it through some more painful side aches had I not focused on my breathing. And yet, the reason I am writing about breathing this morning is because for the past two weeks I have gotten in the elevator at work at least 3 times with this guy. He doesn't come running into the building as he walks in just like I do, and yet he gets in the elevator and is completely out of breath. He sounds like I do after 20 minutes of running. And it's not like he's out of shape, he looks healthy. Anyway, it just reminded me about the importance of breathing, and how lucky we are to not be out of breath, unless we want to be...
