Lack of sleep is not good.
Both Reagan and Thatcher used to brag about how they ran on 4 hours or less of sleep. Years later, it affected their minds.
Sleep is important.

“ Lack of sleep is not good.”

Nope. Yet some of the wealthiest people only sleep a few hours a night.

Just depends on the person. I strongly prefer 7-8 hours, better at 8.

My wife is 4-5, which is how her mom is, at 85. MIL is sadly sharp as a tack and mean.

The antidote must be...Diet Coke! ;-)

Having spent an entire career managing sleep and fatigue, one important lesson was learned. Your body knows what it needs and everyone is different.

I found my sleep cycle (falling asleep, deep sleep, then waking) was 2 hours 35 minutes. I would experience two sleep cycles per night, or day as required.

When I had two full sleep cycles, I was ready to take on a full day. Less than that and I was groggy and needed a nap. More than that, I was tired and it took a lot of motivation to get started.

51/2 hours of bedtime put me at my best. Now that I’m retired and sleeping longer, I’m lazy. Everyone is different.

Joe Biden slept like a log and it didn’t stop his mind from slipping.
