I'm saying that changing sleep patterns and waking up earlier is a very common effect of aging.

YMMV but the idea that you can't grow in/out of sleep patterns is empirically false, and I know this from personal experience.

For most of my life, I didn't need glasses for reading... until I suddenly did. Bodies change.

I knew most of the stuff in that article. If I wake up at 5am on full alert, mind racing, I read for a couple of hours and then go back to sleep when it's possible. I know that I can't function well on less than 7 hours, so I don't try.

The article seems to be taking about people on the verge of entering "the facility", on their slow slide into dementia, who are making do despite not getting enough sleep. I'll get back to you when I hit 70.

I don't know how in the world you got that from the article, but no.
