Two on sleep and aging

When I was younger I remember hearing old people need less sleep. That, at least, was something about aging I could look forward to. But then I wondered: How do they know? Apparently, it was inferred from the observation that old people sleep less. I thought, am I the only one who sees how stupid that is? I don't know about then but not anymore.

"We sleep less as we age because our brains don’t think we're tired: Sadly, there’s nothing we can do about it—yet."

"Aging isn’t killing us, lack of sleep is".
