Cody'sLab : If my math is right, and I’m sure people will let me know I’f I’m not, it would take 96 days of saving a quarter hour each day to have a whole day saved.

Nym Alous : By the way people, that wwwh . umble-pi . com is NOT an error! It is the proper website. If you try to type it with the "humble" completed, it takes you somewhere else. (And I was all excited to think I had caught an error... just does to show you, double-check when you think someone else has messed up, because you might be wrong.)

Joshua Hillerup : I thought most of the deaths are from car accidents.

LimeGreenTeknii : 1:13 "It could give them a heart attack!" Try not to look so excited there, Matt.

Canzandridas Joe : Hearts are the number one responsible for heart attacks

meint48 : In E.U. people kill daylight savings

Un pti com' : Monday is dangerous... We should go back to work on Tuesday !

Helino Friskino : Matt: In my new book, Humble Pi, the comedy of maths errors Me: *goes to amazon, looks it up, book hasn’t been released yet, goes back to the video* Matt: It won’t be released until March 2019 Me: Goddamnit

Steven Augustine : Humble Pi - A Collection of Parker Squares and Other Comedic Math Errors

Mathew Chui : By that logic, since everybody dies, everything either accelerates or decelerates death, nothing actually causes or prevents it. I guess the question is, over what time frame do we decide that something is meaningful or not in a "causal" manner?

Nerdly Squirtly Boy : Cardiovascular deaths is only one possible cause of mortality! Tired driving is deadly driving, I'm sure there's a real effect. Besides, DST just plain sucks. Kill it in the U.S. please.

David Provencher : What about car accidents and other fatigue related deaths?

Erin Cobb : So not heart attacks. Does the less sleep impact things requiring concentration (like say dealing with moving vehicles)? Does productivity go down the one day following the clock change (or vice-versa does anti-productivity go up)?

Aalbert Torsius : How about other deaths? One I've heard pretty often was sleep-deprived motorists causing more accidents after the leap forward.

Eagle Sabre : I don't kill people. I just make them die earlier.

aimee rivers : Isn’t it “daylight saving time”? Like “dog walking time”, no s at the end of “saving” or “walking”.

Imaginary Power : 1:12 Matt being happy about people getting a heart attack

Matthew : By your logic, if I kill a terminally ill patient who would have had a few days to live anyway, I wouldn't have killed them?

Barry Roesch : Saving up 15 minutes per day for 3+ months and winding up with a Tuesday... now that would give me a heart attack.

Niels Schellekens : Nowadays I agree that Daylight Savings Time is less important than in the past BUT the idea of the EU to make every individual country decide if they want to stick with Summertime or Wintertime is absolutely ludicrous.

Lucid Moses : Matt, You should know math better then that. Two points. 1) I have never heard anyone say it was due to heart attacks until you just did. Normally it's said that it kills people due to sleepy driving (at least around here). 2) You were given one argument and you tested a different one. Math doesn't work if you mix up your terms. Check 'Deaths'. That should be way easier then just the heart attack ones. or did you and the data didn't support your claim so you used a straw man Personally I think that sleepy driving will have an affect on accidents. Not sure how that translates to deaths. I would however be interested if you had any evidence to back up your claim that "daylight saving kills people ... is not true" (3:58)

Munjee Syed : Did this get demonitised since it mentions killing?

PapaQ : Lots of people (myself included) have to work both weekends and nights. In my case as a train driver, I will not miss changing the time at all. For us, who are at work as the clock goes forwards or backwards an hour, it can really mess with our work schedules. Time tables are also tricky - passengers sometimes struggle to figure them out on that night. So good riddance, daylight savings time.

Klaas Bil : There's a flaw in your argument. A statement that "something" kills people does of course not mean that otherwise they would have lived forever. Everyone dies, you know. Hence, such a statement really means that people are dying earlier because of that "something" than they otherwise would have. Now, dying a few days earlier from a clock change may not seem like a big deal in the grand scheme of things, but it's not like 0% when considering a whole week is identical to no effect at all. People have still died early!

Flyingby : Here a fitting quote: Never trust a statistic which you haven’t faked yourself.

CAT : 5:03 "Magic square mistakes"

jwrm22 : Great video! I think you should check your humble-pie link. One there is no website yet and it says :)

Thad Spreg : The correct term is daylight saving time (without an ‘s’ on saving).

Meta11axis : haven't read the paper, but here's a quick note: When no statistically significant correlation is found, that does not mean that there is no correlation. In that sense, if the effect is only for a day, and there is no effect on the other days, "diluting" your sample with 7 fold more random data could render the results not statistically significan t enough, even though there is a correlation. The only way to be sure what you claim on your video is true, is if they found an opposite correlation looking at the rest of the week days, not if they found no statistically significant correlation during the whole week.

Gonçalo Sanhudo de Portocarreiro : "More people are dying, but only dying earlier." 🤣🤣🤣🤦‍♂️🤦‍♂️🤦‍♂️

Tiikoni : Since this clock moving takes place during weekends, and almost all my devices (computers, phone, radio thermometer) does it automatically, I've several times moved between dst and normal time without even noticing/remembering whole thing.

CapriUni : Yeah, Okay. Mathematically, it evens out to be zero net change, overall. But if I'm going to die of a heart attack anyway, I'd rather it were a few days later instead of a few days earlier. (I remember being a kid in 1974-'75, during the American Energy crisis, when they decided to make Daylight Savings last all year ... and from October through March, or so, we rode the school bus to school in pitch dark ... and we had safety lectures for the kids who walked to school on how not to get hit by cars. ... Yeah, that experiment wasn't repeated. And then, in his second term, George W. Bush tackled another energy crisis and fought global warming by extending Daylight Savings at either end. So now, in America, it's a full month longer than it is in the EU). So that's another mathematical claim to check out: does it really save any energy?

palmomki : Didn't non-nihilistic people consider extra hours of life to be sacred and so on? I think the common morality sense dictates that accelerating someone's death is very close to just straight up killing them, unless it's euthanasia of course. So from this perspective, even if what you bring up here is true, it just means that daylight savings are immoral in a different way, and a way that's actually not too far from "daylight savings kills people". In fact, not only that: it possibly means that having to wake up every single day to get to work might be escalating heart attacks all over the world, stealing a whole lot of lifetime. Yay society.

The Montage : Matt, I take your point. I think however that you are missing the point. When people actually get to sleep just a little more than usual, their health will likely improve. That is due to the restorative powers of sleep for your mind and your body. Conversely, when we lack sleep, we become unhealthy. The fact daylight savings shift warps that stat at all is testament to that. As the old saying goes "sleep is the best medicine". If you haven't already, I think you would be fascinated by the writings of Matthew Walker, especially his book Why We Sleep: The New Science of Sleep and Dreams. He talks about this stat, and puts it into a larger context! (As well as many more, which I welcome you to debunk if they turn out to be false)

coryman125 : "Less sleep only kills people that would have died anyways". In a sense, that's always true. Car crashes only kill people who would have died anyways. Also wow that's very morbid

Evi : 1. days with an extra hour have 4% more deaths in that day 2. nothing really kills people, it just makes their deaths happen earlier then they were going to anyway

ReVoLynx : Well yeah, the number of deaths doesn't change. The number of deaths is always fixed in the long term, because everyone who is alive will eventually die. It is just a matter of when. Short term results do matter to people aswell. I'm sure it would make a difference to you whether you had a heart attack tomorrow or a week from now.

GFmanaic : But it is written in white letters filling the screen in a video on youtube, it must be true !`

Wizmut : Wish the gov didn't bully us into changing our clocks. If people want winter hours... isn't that up to themselves?

Nathan Bonnell : Ummmm... Heart attacks are not the only way people die from lack of sleep. Motor vehicle and workplace accidents go up after the change in time. Daylight savings time DOES kill people. It also lowers productivity, and is just really inconvenient for everyone.

Wouter Cloetens : So, if we can reduce heart attacks by letting people sleep an hour longer, then the responsible thing to do would be to do that every day. Let’s shift to a 25 hour day rhythm!

Alex : But why should we average out the week? What if we average the whole period of daylight savings?

Jimmy De'Souza : That the increase/decrease is essentially nullified by the rest of the week doesnt make sense really. I wonder if the effect is actually some kind of administrative artifact with how instances are recorded...

Looking In With Victor B : Preordered your book, although with tiday's exchange rates, I am paying and extra 33%

Voshchronos : Damn, that's what plagues statistics. Even if the math is right, you can interpret it wrong with disastrous consequences.

Mad Scientist's Assistant : I wonder about other health concerns like car crashes and stuff like that.

Existenceisillusion : Sooo...the EU is finally realizing what Hawaii and Arizona have known all along? I say it's about time.

Pixie Panda Plush : (0:40) I will complain that your graph is wrong. The way you made it does not apply in EU, not in UK, not even in USA. The agreement we have in EU currently is that at 1:00 UTC, the clock moves forward to 2:00, and at 2:00, the clock moves backwards to 1:00 UTC. The effect is that the clocks always changes at 1:00 UTC; you leave 1:00 UTC going into summer time, and you arrive at 1:00 UTC when leaving summer time.

Pixie Panda Plush : (0:07) Correct me if I'm wrong, but I'm sure they said that _if_ they were to remove the switching between daylight saving, it would occur in 2022 earliest. The date in 2019 is the deadline for the decision, not for when the decision is taken into effect.

Captain Cringe : All I got from this is that we could have daylight savings every day and perpetually push people's heart attacks until the proverbial tomorrow, thereby eliminating cardiac arrest completely. Besides, I get tired of hot tar roofing in daylight anyway; might as well cycle it to nighttime about every month.
