Life Span, old age, and statistics

The issue before last of the National Geographic featured an article on the Teenage Brain. This past issue, which arrived last week, included a letter to the editor from a reader who somewhat grumpily suggested that the teenage brain might be the evolutionary norm, because, he suggested, back in our early days as a species, we didn't live much longer than that.

Oh yes we did.

The suggestion of the letter writer was that human beings live longer than they used to. This is a common belief, people state that all the time, but it simply isn't true. People live the same number of years that they always have. That number of years varies by population and culture, but it's generally between 60 and 120 years. Extreme old age generally seems to cap out at an absolute maximum of 120 years, a span that's actually mentioned in the Old Testament, interestingly enough. The longest any human in modern times has been recorded to have live is 122 years. There are claimed examples of people living in excess of this number of years, but they lack verification and tend to be subject to serious questioning. This is not to say, of course, that anyone can live to 120 years. Far from it. Only a tiny minority of people shall ever approach that age. But instances of advance years in any one era are quite easy to find. Chief Washakie, for example, lived to be 99 or 100 years of age and was not the only Native American of that to have done so. Adams and Jefferson lived into their 80s. And so on.

Well, if people are not actually living longer, why do we tend to think that we are? That's because life expectation is increasing. That is, average life span, or life expectancy, is increasing.

Well, isn't that the same thing? Not at all.

Life expectancy or average life span is a statistical figure. It doesn't mean that all people live to that age. No, by its very nature it means that most people will have died before that age or after it. It's the statistical medium.

But if that's the case, wouldn't it still mean that people are living longer? No, what it means is that people aren't dieing as young.

That sounds like semantics, but it isn't. When you look at what killed people in prior eras, it makes sense.

For one thing, and a huge thing at that, an enormous number of people died at (and in) child birth prior to the mid 20th Century. And this was in European and North American societies. Infant death was very common. Childhood death was also distressingly common. A large number of people died prior to age five.

The reason for this is varied, but disease and the stress of birth explains a lot of it. But what it also means is that if a person passed their fifth year, their life expectancy jumped enormously. Indeed, if you take out the number of infants who died prior to age five, and the number of women who died giving birth, life expectancy for the most part would begin to look pretty recognizable for most European or North American cultures.

They would not, of course, be identical. But that's easily explainable as well. Diseases of all types were enormously dangerous prior to the late 19th Century. The germ theory of disease itself was only discovered in the mid 19th Century. There were an awful lot of diseases that, if you acquired them, your end was nearly guaranteed, where as this would not be the case now. Heart attacks, cancer and strokes basically killed. Diagnosing dangerous diseases prior to their last phase was often impossible. None of this is true now. And accidents tended to be much more lethal in any era prior to the one we're living in right now. Work, for males, was much more dangerous in prior eras.

And, of course, warfare was very prominent in earlier eras. Most European nations were constantly at war in the 18th Century. When the Indian Wars are included, the US was basically at war from 1776 through the 1880s. And wars have become less lethal in modern times in comparison to prior eras.

So what does all this mean? Perhaps not that much, but the common modern assumption that we're living longer is simply incorrect. Things aren't killing us before we reach our natural end of life. That's what is occurring.

Today In Wyoming's History: January 27

Today In Wyoming's History: January 27: 1943 Contact was reestablished with Jackson after the town had been isolated due to a snowstorm. The period of no contact was six days.

This was not really an unusual event at the time. Prior to advancements in 4x4 vehicles, brought about due to World War Two, it was nearly impossible to remove significant amounts of snow from mountain passes, and towns located in mountain valleys were routinely cutoff from contact with the outside for days and even weeks. This was particularly true for Jackson. Indeed, this was so much the case that a book written in the 1950s, by a screen writer who lived in the town off and on during the 40s and 50s, maintained that the "Cocktail Hour In Jackson Hole" was the entire winter, as the town was completely cutoff from the outside during that time and engaged in one huge party all winter long. No doubt that was an exaggeration, but there was some truth to the statement.

Less romantic, an irony of the situation is that up until 1970s Jackson was not regarded as a particularly desirable place to live. This was very much the case prior to 1950. Prior to 1950 agriculture, together with government agencies, formed the economic base of the town, but even there the homesteads that had been filed there were very late ones and were not the most enviable to have, as the ranches in the valley had to combat the weather and were so extremely isolated. It is only the modern 4x4 snow plow that has made Jackson the winter vacation spot it is, and by extension the home of many wealthy people.

This topic closely relates to some others here about the end of the horse era. Given the exploration about horses in urban and agricultural use, this topic may be particularly interesting in the context of the topics we try to explore here.

Today In Wyoming's History: January 1. New Years Day

Here's the January first entry from the Today In Wyoming's History companion site.

Today In Wyoming's History: January 1. New Years Day: 1863 Daniel Freeman files the first homestead under the newly passed Homestead Act. The homestead was filed in Nebraska.

While the original Homestead Act provided an unsuitably small portion of land for those wishing to homestead in Wyoming, it was used here, and homesteading can be argued to be responsible for defining the modern character of the State.

As noted, the Homestead Act has had a huge, and continuing, impact on the State's history. That's probably self evident to most students of history. But it occurs to me also, for some reason, that the Homestead Act is more representative of a bygone age than perhaps we'd care to imagine.

At the time the Homestead Act was passed, in 1863, obtaining land on the cheap, indeed nearly free, had been the American rule since Jamestown. What the Homestead Act really formalized is the granting of Federal Domain in an orderly fashion, seeking to encourage people to move West. It says something about the Union that it could afford to take this step during the Civil War, which in 1863 was only at its mid point. You wouldn't think that the country would be encouraging some of its citizens to pull up stakes and move West at that time, but it did.

The Act, or rather various Homestead Acts, continued on in force until 1934. The peak year for homesteading was 1919. But even the demise of the Act in 1934 did not mean that land was unavailable.

That's really changed. It'd be difficult, if not outright impossible, for the poor or nearly poor to take up farming today. Indeed, it isn't easy for the Middle Class to do so, or at least not in a serious manner. That's an enormous change in the nature of the country.

Today In Wyoming's History: January 2. The Legendary Blizzard of 1949

Nobody who lived through it ever forgot it. Whenever my father and his contemporaries turned towards discussing the weather, it came up. The Blizzard of 1949, which started on this day, and lasted for a month in one form or another.

Today In Wyoming's History: January 2:

1949 Beginning of the Great Blizzard that struck the Northern Plains this year. In Wyoming, the storm started on this date and lasted until February 20. Snowfall in some areas measured up to 30". The storm halted all inter town transport of all kinds within the state within 24 hours. Seventeen people died as a result of the storm. 55,000 head of cattle and 105,000 head of sheep were lost.

Today In Wyoming's History: January 2. It must have been quiet, or at least different, before that.

Today In Wyoming's History: January 2: 1930 First commercial radio station in Wyoming begins operation. KDFN later became KTWO and is still in operation.

Hard to imagine an era with no radio. But Wyoming lacked a commercial radio station until 1930. This was a Central Wyoming station (or is, rather, it still exists). I'd guess Cheyenne could have picked up Denver stations by then, but in Central Wyoming, having an AM radio prior to 1930 must have been pointless.

Today In Wyoming's History: December 23. A Plague of Rabbits

Today's Today In Wyoming's History: December 23:has a couple of interesting items related to hunger. those being:

1926 1,000 rabbits show near Medicine Bow and sent to Rawlins, Wyoming, to feed the hungry.

1935 5,600 jackrabbits killed in Natrona County in one of the periodic Depression Era rabbit drives that were designed to help feed hungry families. Amongst the numerous natural disasters inflicted on the nation during the Dust Bowl years were plagues of rabbits. Attribution. Wyoming State Historical Society.

The 1920s entry surprises me, but the 1930s one does not. These events were amazingly common in the 1930s.

The Great Depression, of course, threw millions out of work, and desperation set in for many. Oddly enough, at the same time that the country was hit by one of the worst depressions it had ever seen, an event that was global in its scale, the environment seemingly went after people as well. Summers in the 1930s were very warm, and very dry, rivaling some of the worst of that type we've seen recently. Winters were warm and dry as well. This created the dust bowl conditions that are so strongly associated with the Dirty Thirties. But beyond that, farming entrants onto the Federal domain in the teens and twenties, sparked by a wheat boom caused by World War One, farmed areas with "dryland" farming that were never suitable for it. This turned the fields into fields of weeds by the early 30s, and the wheat boom caused a rabbit boom in regions that had only recently been prairie. Plagues of rabbits were the result. By the 1930s, addressing rabbits was a major concern in the West, which in turn oddly coincided with the hunger of the Great Depression, leading to winter rabbit drives.

Histories, early and late. Was :Today In Wyoming's History: December 20

Today's Wyoming history entry presents us with the troubling and interesting question of how history can sometimes be a bit skewed, depending upon who is looking at a topic, and when. That entry appears below:

Today In Wyoming's History: December 20: 1812 One of the dates claimed for the death of Sacajawea. If correct, she would have died of an unknown illness at age 24 at Fort Manuel Lisa, where it is claimed that she and her husband Toussaint Charbonneau were living. If correct, she left an infant girl, Lizette, there, and her son Jean-Baptiste was living in a boarding school while in the care of William Clark. Subsequent records support that Charbonneau consented to Clark's adoption of Lizette the following year, although almost nothing is known about her subsequent fate. Jean-Baptiste lived until age 61, having traveled widely and having figured in many interesting localities of the American West.

The 1812 death claim, however, is rejected by the Shoshone's, to which tribe she belonged, who maintain that she lived to be nearly 100 years old and died in 1884 at Ft. Washakie, Wyoming. A grave site exists for her, based on the competing claim, in Ft. Washakie, the seat of government for the Wind River Reservation. This claim holds that she left Charbonneau and ultimately married into the Comanche tribe, which is very closely related to the Shoshone tribe, ultimately returning to her native tribe This view was championed by Grace Hebard who was discussed here several days ago, and it even presents an alternative history for her son, Jean Baptiste, and a second son Bazil. It was later supported by the conclusions reached by Dr. Charles Eastman, a Sioux physician who was hired by the Bureau of Indian Affairs to research her fate.

While the Wyoming claim is not without supporting evidence, the better evidence would support her death outside of Wyoming at an early age. The alternative thesis is highly romantic, which has provided the basis for criticism of Hebard's work. The 1812 date, on the other hand, is undeniably sad, as much of Sacajawea's actual life was. Based upon what is now known of her story, as well as the verifiable story of Jean-Baptiste Charbonneau, who had traveled in the US and Europe, and who had held public office in the United States, the Wyoming claim is seriously questionable. That in turn leaves the question of the identify of the person buried at Ft. Washakie, who appears to have genuinely been married into the Comanche tribe, to have lived to an extremely old age, and to have lived a very interesting life, but that identity is unlikely to ever be known, or even looked into.

Now, quite frankly, I do not hold to the view that the "victors write the history", or that all history is written with the view of justifying the views of the writer. Quite the opposite is generally true, and for the most part, most good histories get things right more often than wrong. That, however, may be part of the problem here. The early history on the Wyoming claim was promoted by Grace Hebard, and as remarkable as she was, she not only was not a trained historian, but it would appear not a perfectly unbiased one. And it would also appear that her research did not benefit from delving into the existing sources much. So she concluded that a woman who likely was a very interesting long lived Comanche-Shoshone woman was Sacajawea, when in fact she almost certainly was not. Beyond that, Hebard went on to make Sacajawea sort of a feminist icon, which perhaps does not really do justice to a person who was an unfortunate girl at the time she was ripped away from her home in a raid, and who was later married as the second bride in the polygamist household being then maintained by Toussaint Charbonneau (what happened to Otter Woman, the first Shoshone bride of Charbonneau, I do not know). Dying from illness at 24 years old was a bad fate, but one that was pretty common at that time, so the truth appears to also have a pretty unfortunate ending to a pretty hard short life.

So what does this whole story tell us now? Well, perhaps it says something about the very early written histories of places like Wyoming, where a lot of the very early writers were very dedicated and energetic, but not always unbiased, and sometimes over enthusiastic. Perhaps this also points out why new histories are sometimes needed, and sometimes more objective than earlier ones. The first on the scene sometimes have an agenda or a viewpoint that can't help but dictate the outcome of their work, and they may not even be able to recognize that their work is so influenced. And it may also say something about holding on to a myth against all odds, as Wyoming still claims the 1884 death, in spite of the best evidence all being to the contrary. I suppose it also says something about drafting works of history without adequate research as well.

Today In Wyoming's History: December 14. Grace Raymond Hebard

Today In Wyoming's History: December 14: 1914 Grace Raymond Hebard became first woman admitted to state bar.

This was a remarkable achievement in and of itself, but it only one of a string of such accomplishments made by Hebard. She was also the first woman to graduate from the Engineering Department of the University of Iowa, in an era when there engineering was an overwhelmingly male profession. She followed this 1882 accomplishment by acquiring a 1885 MA from the same school, and then an 1893 PhD in political science from Wesleyan University. She went to work for the State of Wyoming in 1882 and rose to the position of Deputy State Engineer under legendary State Engineer Elwood Mead. She moved to Laramie in 1891 and was instrumental in the administration of the University of Wyoming. She was a significant figure in the suffrage movement, and a proponent in Wyoming of Americanization, a view shared by such figures such as Theodore Roosevelt.

She was an amateur historian as well, which is what she is best remembered for today. Unfortunately, her historical works were tinged with romanticism and have not been regarded as wholly reliable in later years. Her history of Sacajawea, which followed 30 years of research, is particularly questioned and would seem to have made quite a few highly romantic erroneous conclusions. On a more positive note, the same impulses lead her to be very active in the marking of historic Wyoming trails.

While she was the first woman to be admitted to the Wyoming State Bar, she never actually practiced law. Her book collection is an important part of the University of Wyoming's American Heritage Center's collection today.

What amazes me about this article is that he's only the eighth lawyer to hold that position, which includes the other three presently holding it, and Judge Downes who recently retired. That means 50% of those holding that office are still living
