I knew I should have picked some cider vinegar yesterday at the health food store.

On a related note, years ago, I was introduced to a concoction called Jog In A Jug. It was(is?) a combination of frozen Welch's grape juice concentrate, frozen apple juice and apple cider vinegar, more or less in equal proportions and mixed like regular juice. It's supposed to fix what ailes ya. I tried it, and don't remember feeling either better or worse with it. I quit because it was just one more responsibility when I was overwhelmed. I've been considering picking up the habit again, with my aching knees, and all. It can't hurt, can it?
