Several of the women I know here on the forum are 70+ years of age. I'm one of them, and I can tell you that after a certain age, sitting can become debilitating. Not saying that standing as opposed to sitting burns more calories, but saying that thousands of tiny muscles need to be used every day after a certain age. Muscles in the ankles in particular help us keep our balance.

Even 5 years ago, it was totally different for me.

Old people who sit in recliners most of the day end up having to sleep in those very same recliners because they're unable to get up out of them any more.

Movement is very important.
