Yesterday (or perhaps Friday, or perhaps both), I went outside to fetch the mail, saw that the top of the trash cart was conformally coated with ice from gutter runoff again, and discovered that the continuing improvement in my knees is such that I could crescent-kick the cart free of ice. (Yes, I may have done it two days in a row. I'm not entirely certain at this point.)
Today, I think my right knee is telling me what while I can, this doesn't mean that I should unless I really need to...
