Paradoxes of breath

If "Paradoxes" is the correct plural version of "paradox". I doubt it is. Can I ever be right about something like this? Haha. Almost like how right I can be about tests. Which isn't much.

Breathing sucks when you're sick. Right now, my sinuses are clogged, nose is stuffy, and it's just no fun. Had me thinking about the realities of breathing however many times per minute, per hour, per day, per lifetime. All the energy consumed by muscle as it expands and contracts. How much of that energy is lost due to inefficiency... For an evolved creature, we're so fucking inefficient. In physical ways, we can't do much about, but in general... We could make things so much better than they are, but... We don't care.

All we seem to care about is what we put above each other.
