http://www.TheSparkAndTheArt.com/132 - I heard a quote earlier this week and I can’t find it anywhere online so I don’t know who said it or in what context but I’m gonna talk about it anyway because it got me thinking.
The quote was something along the lines of you can’t both breath in or out. Basically meaning you can’t do only one. You can’t only breath in. Your lungs can only hold so much. The oxygen is all absorbed and gets stale. Your lungs ache and eventually you breath out
