Grandpa Joe used to talk about being all 'stove up' I never got that one either. Until recently.
What he meant, speaking in general terms, was that when you had been active for a while and then sat for a while, your muscles tightened up. You became stiff and sore; achy. It might take a few steps before you were walking comfortably because your joints weren't limber.
Well, after curling the last two days I came to realize exactly what Grandpa meant. Immediately after each game I felt okay, but well after each game as I stood up from the table after a pint and a bit to eat, my back was tight, my shoulders sore, my knees aching, and it took about 15 steps to walk fully upright comfortably. I was all stove up.
Sometimes you just have to experience something to get it.
