Yeah, but it's not just because of the huge drop in infant and childhood mortality. A lot of older people are able to live much longer too thanks to modern medicine. This also creates a skewed view due to the differences of healthcare infrastructure between the developing world and industrial countries.

This might be an unpopular opinion, but I think it makes perfect sense for human life expectancy to ignore infant mortality as well. It varies so much from country to country and time period to time period that it throws off the final number big time.

It bears mentioning that the very low infant mortality rate of humans is almost entirely due to modern medicine as well as sociological changes that lead to people having few babies. Infant mortality and childhood mortality was very high in pre-industrial time and it's on account of modern hospitals, professional midwives, better health and safety, and modern medicine in general that people now almost certainly can expect to survive both growing up and giving birth.

Tbf, *most* things are better represented as higher-resolution continua and fields than as a single number. If you break down life expectancy to the month, then you can also probably see more about reproductive cycle, since more babies happen in the spring and more deaths happen in the winter (so you should have slight drops in the survival graph at, e.g. 0.5, 1.5, 2.5, etc).

I think there's a mistake on the website. The oldest living cat was 46, not 38. Edit: I had read a book from my library that showed the picture of a cat that had lived to 46. It was a really long time ago and a very old book. I think maybe the information about this cat wasn't wide spread enough to get on the internet since it was documented before that time. The cat was a brown tabby with yellow eyes. I want to say it lived in Texas, but I can't be sure. It's hard to remember exact details from that long ago.

Thank you 😍

This is such a good breakdown on why it is a flawed system yet many people are intimidated by graphs and as such would ignore it compared to looking at a single number which is easier to understand. The value is meant for the general audience. For all practical purposes, when most people think of average life span, we think of dying from "old age." As the video mentions, it is mainly due to the fact that most people only pay attention to domesticated animals. Turtles dying due to predators doesn't fit that conception. Neither do infant mortality. So for species that have a lot of deaths from other causes, we tend to ignore them. As for humans, we aren't dying to these other causes as much nowadays so it tend to not be a big deal even if we include them. Additionally, human lifespan is often used as a tool to educate the public about improvements in medicine and safety. To do that, we need to include all causes of deaths into the calculations. If we ignore infant mortality, disease and war; medieval lifespan would be similar to our average modern lifespan. But that would not convey the fact our lives are much better now, so the given value is based on all deaths unlike other animals. To kind of conclude, the inconsistency IMO is introduced in order to communicate certain points across to their audience. Not very genuine but most laymen don't like to look at charts, so a easy to understand value is usually given. Telling people their pet turtle will die in 3.5 years would be bad because their pet turtle won't die in 3.5 years since there's no predators. It's just not relevant, and science communication is meant to provide relevant information in a easy to understand format so people can make informed decision.

Death note reference at 0:51 👀

There is no such thing as maximum life expectancy, because life expectancy is what is called in probability theory an expectation - it's an average of the lifespans. Also, in a quick google search I didn't find the number 80 associated with the life expectancy of sea turtles (I found 30 and 50 which are also wrong but I don't know where you saw that number associated with turtle life expectancy), because it's not the life expectancy, it's the maximum known lifespan.

Thsts craxy

I've wondered for a long time if counting human life expectancy from birth is really a good idea. I seem to recall that's behind the apparently false impression that 40 years old would have been like 80 years old back in the day, when actually it was more that the midwives back then weren't as good as contemporary doctors at ensuring babies survived, so a lot of them would die. I also think (I heard this a long time ago, so it might be mistaken) that part of the reason men have a shorter life expectancy is because of the greater likelihood that they'll die in battle or in accidents during dangerous work, but hearing that will make it sound as if a man will probably die of natural causes earlier than a woman. I've always thought it might make more sense to count life expectancy as "the average age of death given an untimely death does not occur". That's what people often seem to read it as (hence some media having jokes where the 40-year-old is called unbelievably ancient), and it's kind of misleading to be told "this is the age you'll probably die" if the number is skewed by odds that something's going to happen to you. Basically, I think the principle behind applying dogs' life expectancy differently actually does apply to humans too, and maybe statisticians/scientists should take that into account. Especially for the past, when people were losing a lot more babies than now, and the difference between those two methods was probably quite a bit more significant.

Nice video Support from CuriousPhysics channel 💯💯💯💯

Can we chart the curve of the graph and use an equation to describe life expectancy? That would be accurate AND make complex math more relevant in real life.

Yeah, tbh that makes sense. I think that on a surface level it works as is, but the curves give a lot more nuance.
