You have a worse sleeping schedule than mine dude and thats hard to achieve considering I can wake up at 10

I run on about 4 hours sleep 🤷🏻

I run on 4-6 depending on how much I feel like pushing it

Ooh, is this the insomniac off?

Am I too late?

I can't really run on anything less than 7 hours TBH

(for the most part)

there are times when I'll be able to run with like...2-3 hours sleep

Running on 4 hours sleep is not normal. There was a recent survey that found certain people have a gene where they only need 4 hours sleep, but its not a common thing. Margret Thatcher quite famously was most likely one of these people.

I guess the gene was never advantageous until modern lifestyles and lighting came into existence

would be bloody handy now

for those of us not running on 4 hours unless they take multiple 4 hour naps a day

Nah, I'll routinely go 24+hrs on a 4hr rest

It would be useful, but not nearly as useful as the uber productive society we live in today.

In the past they merely would have made good guards around the camp/town

The main limiting factor is, how productive can you be at night?

Quite

3,000 years ago?

Today we have lightbulbs

You can train night vision

To read in the dark?

Yep

Bullshit

I do

It wouldn't be something reliable.

moonlight for maybe 25-50% of the time

And you'd strain your eyes. You could read a report, but reading a book.

Moonlight...

Go out and pitch a fucking tent, and read in moonlight.

well I'm not suggesting reading

Don't be so fucking silly

there are better things to do at night

with sufficient light from moon

With how many people it requires to do useful activity's and the risk of harm or unjury its just not worth it.

Maybe you could do it as a one off thing, but consisting finding a productive activity to do a night? Name 1

no you have to go all out during the daylight because there isn't time to waste

so if you have night time to reflect and improve strategy, bigger returns moving forward

but that would be assuming your brain isn't doing similar things while you sleep

🤦🏻

waking hour optimizations might be inferior to what occurs in sleep

also anything in the arts/sciences etc would be productive at night
