“A lot of people like to brag about how they only need 3-4 hours of sleep nightly, while disparaging others who seek a good 8 hours.
“used to know a braggart like this, but he’s now deceased. (at age 50-something).”
Zero of them, made it much past age 60.
My wife saw similar results with other students in her high school class and classes in her RN school.
I’m 86 and my arteries are fine. Of course, I usually get 9 - 10 hours sleep at night. Have my phone set to “silence” calls before 9:30 a.m.. It’s 10 here now, and I’m just having coffee. Yawn
