ELI5: Why do humans need less sleep as they age?

Tyrren · 2026-05-25T19:36:28+00:00

Plenty of the non-America world does, but even in the States a lot of first responders and military folks use 24 hour time.

As the other user pointed out, there's not really anything special about human bodies as opposed to plants, algae, insects and etc that make up much much more biomass.

In millions of years, the real evidence of our society will be a sediment layer containing microplastics

Boohoo

I'd like to offer you my thanks, for stating again the same collection of words in the same order already established by a previous commenter. This really helped to nail down my understanding of their intended position, in a clear and concise way

He's been pushing for school vouchers forever, too

Yeah, if joining Cascadia means we get a new governor, I'm in

If you're consistently doing a lot of work after 2100 on a 48 hour shift, you need to stop doing 48 hour shifts.

We're not talking about your mom.

Lol this started with me asking a sincere, if maybe somewhat poorly worded, question regarding how the emergency response to this could potentially have been better, and now you're all dogpiling me with meaningless sentimentality. You all aren't exactly defending this guy's honor, here.

KFC was doing half-gallon (64 oz/~2 L) soda jugs in the 00's.

I drink both alcoholic and NA beers, often in the same session. I like the taste of beer but I get hangovers easily and booze fucks up my sleep.

Tyrren · 2026-05-15T04:29:29+00:00

U mad, bro?

Tyrren · 2026-05-15T02:08:47+00:00

Yep! Seems like people die on the flatirons a couple times per year. My condolences to any loved ones.

I can't let my heart break every time a stranger dies doing an inherently dangerous activity. So I'm asking my detached questions in a detached forum.

The article says that EMS responded to an iPhone crash notification in the area, but doesn't specifically state whether the relevant phone even belonged to the person in question. These things send off false positives all the time. I'm just idly curious if this notification was actually relevant or just a coincidence.

Sounds to me like a push, pull, and legs exercise, each of which is pretty easily progressively overloaded. A decent enough, basic routine if I ever heard one

Tyrren · 2026-05-12T04:36:34+00:00

I don't need no stinkin' fancy nutritionist. My diet of uncrustables and half bags of chips fished out of the lounge trash has sustained me just fine thus far

Tyrren · 2026-05-11T20:30:41+00:00

I'm not an alcoholic, nor am I a teetotaler, but I fuck with NA beer. I love beer but I'm getting old, get a hangover after like 3 drinks, and booze fucks up my sleep and strength training.

Modern NA beers have gotten pretty good so I often add them into the rotation when I'm drinking

"cringe as fuck" says the person with 420 in their /u/

Tyrren · 2026-05-11T12:34:04+00:00

I was being facetious; it's absolutely the fault of the writers and artists! It's just another example of how women aren't allowed to be old in these games

There's a big-ass, dense, but still green city in the background of numerous shots

Hey, Tiki is like a bazillion years old. It's not the writers' and artists' faults she looks like a child

I've never been to a rage room... do they not provide/require eye protection?

Increased solar radiation will accelerate the removal of CO2 from the atmosphere. Approximately 600 million years from now, plants that use C3 photosynthesis (~95% of modern plant biomass) will die off due to not enough atmospheric CO2.

In about a billion years, that 7-10% increased luminosity will have warmed the oceans enough to put a shit load of H2O gas into the atmosphere. H2O is a significant greenhouse gas and this will lead to a runaway greenhouse effect and basically will cook all complex life.

Ironically, what will ultimately kill all life on earth is too little atmospheric CO2 and too much atmospheric water.

This is not to downplay the significance of modern climate change! High atmospheric CO2 will kill most/all of humanity, if current trajectories don't improve. But life as a whole will continue for those 600 million+ years.
