At the end of most of my yoga classes, I close by asking us to take a moment to "thank our bodies for the hard work they have just done and have gratitude for the hard work they do for us every day, all the time, without us even knowing it", or words to that effect.

I don't know about you, but I'm miffed when I can't do a yoga pose. It bugs me when my leg won't neatly slide behind my head and I can't then balance on my index finger. When in reality, the fact that I can even lift a leg is an amazing feat of engineering and yet here I am complaining that it's not high enough.
