Surgery today to remove some lesions from my scalp (let's not use any word beginning with "c"). Not supposed to get *any* exercise for the next few days. But I've been walking a few miles a day, and I still did it today, it's too nice out and I'm too bored otherwise. I'm making an interpretation that "the next few days" doesn't include Sunday.
I could definitely feel yesterday's core strength exercises just under the ribcage. So something did come out of it.
