|Pig-pen, or spontaneous human combustion in my bike lane|
When you are riding and notice that you're about to pass through a cloud of thick dust, do you hold your breath? I often do, but then, I wonder, what if I can't hold it all the way through, is the deep inhale within in the cloud worse than just breathing normally and going on through? I've done it before, seeing a ginormous diesel pickup belching gray smoke as it tears away from a stop sign, and not wanting to breathe deep of its fragrant exhaust, held my breath, only to find myself still within its effluent upon running out of air, and thinking, how many microns are those tiny particles in diesel smoke that nestle deep in your lungs for life? Would it be worse, in the long term, to hold your breath until you passed out and fell over, rather than breathing in that stuff? These are my thoughts on some days. Am I the only one?
