Do you breath?

In the wee hours of the morning around 5am I walk. Right now it's just before dawn so there is not a lot of things to look at and a lot of time to take note of weird things like breathing. I've also been doing a little yoga. A real little like five times a week for 12 minutes. I've been working on cordinating my breathing with the exercises and I've noticed I've seperated my lungs from my diaphram. I'm not sure how this happened was I stressed and just took shorter breaths? Possiblie counsious of my stomach and in a need to keep it tucked in managed to separte them? Maybe an entire enflamation of my gut that has totally been too painful to think about? A combination???? Anyway that's were I am today. Now I'm consciously trying to breath with my diaphram and it feels like I have a third lung and sometimes I get light headed or feel like my lungs are expanding and my diaphram is contracting it's a weird weird experience. Nice to not have such an inflamed gut that has a constant low pain and nice to enjoy belly breathing again.
