I can vouch for the fact that Linda's "roll" has definitely slowed. But guess what? She has a bad day, another bad day, another and another and she looks like she has sunk about a foot further into the couch. Then, wait for it --- a good day comes along. Well, I can just tell you this lady looks like a different human being altogether! She is running around our place with vacuum in hand, here, there, oh, and over behind there. Next I hear the washing machine running. Then she is involved in god knows what other project in the kitchen. An hour later I emerge from my hole to see this small mound of something on the couch. Oh, its her. Yes, she spends it like the proverbial hole in the pocket, and its gone. Do people ever actually learn? She says to me, "If I am feeling energy I have to DO SOMETHING".😒
