Taking a breath for better health (2013)
Journal Article
Killard, A. (2013). Taking a breath for better health

What does your breath say about you? It might tell the world (or at least anyone at close quarters) that you didn’t brush your teeth this morning, or that you ate garlic last night. But there might also be other, subtle and important clues in there a... Read More about Taking a breath for better health.
