All my buddies laugh when I stretch, but I haven't pulled a muscle in years.
I see many farriers start shoeing without any warm-up. I do ten minutes of stretches first, and my back and knees thank me later, despite the jokes. Do you think warming up is worth the time?
That bit about throwing out his back is no joke. My neighbor did the same thing just getting out of a chair after a long laugh. It's crazy how a simple, happy moment can just break your body. Makes you realize we're all just held together with old rubber bands and hope. Getting old is basically your body finding new and weird ways to betray you.
