A Most Interesting Data Set Covering the Longevity of Polish Elite Athletes Across Much of the 20th Century – Article by Reason

The New Renaissance HatReason
******************************

Today I noticed an open access paper in which the authors examine mortality data for Polish Olympic athletes over the past 90 years or so, and compare it with established historical data for the general population. This blends two topics that are occasionally covered here at Fight Aging!: firstly, the growth in human life expectancy in recent history and its causes, and secondly the topic of how regular exercise and life expectancy interact. It is the present consensus that elite athletes, those at the top of their profession, live longer than the rest of us, but it remains open to debate as to whether this is because more exercise is better, or because very robust people who would have lived longer anyway are more likely to enter the world of professional athletics. Researchers want to map the dose-response curve for exercise, in other words. Even though there is very good, very solid evidence for the benefits of regular moderate exercise versus being sedentary, going beyond that to a more nuanced view of what more or less exercise does for health is a challenging goal given the starting point of statistical snapshots of data from various study populations.

Studying the history of life expectancy isn’t much easier, though there the challenges tend to revolve around the ever-decreasing quality of data as you look further back in time. The 20th century marked transitions from hopeful aspiration to solid accomplishment in all fields of medicine, too many profound advances in the capabilities of medical science and practice to list here. As the decades passed, this important progress focused ever more on treatments for age-related conditions. An individual born in the US in 1900 suffered through the end of the era of poor control of infectious disease, prior to modern antibiotics and antiviral drugs, and likely benefited little from later progress towards better control of heart disease and other common age-related diseases. An individual born in the US in 1950, on the other hand, enjoyed a youth with comparatively little fear of disease, and is probably still alive today, with access to far more capable therapies than existed even a couple of decades ago.

Given all of this, one of the interesting things to note in the analysis of the Polish data is that the elite athletes born in the early 20th century appear to have a lower rate of aging than the general population, as determined by a slower rise in mortality over time, but that this difference between athletes and the average individual is greatly diminished for people born in the latter half of the 20th century. This suggests, roughly, that advances in medicine from 1900 to 1950 had a leveling effect, bringing up the average, preventing early deaths, but doing little to address age-related disease. That said, there is a large variation in results across the range of similar studies, both those that look at the history of longevity, and those that look at populations of athletes at a given time. It is wise to consider epidemiological studies in groups rather than one by one, and look for common themes. Still, this one is a fascinating data set for the way in which it combines historical trends and exercise in the study of aging.

Examining mortality risk and rate of ageing among Polish Olympic athletes: a survival follow-up from 1924 to 2012 – by Yuhui Lin, Antoni Gajewski, and Anna Poznańska

Quote:

A sedentary lifestyle is associated with the onset of chronic diseases including ischaemic heart disease, type-II diabetes and neurodegenerative diseases. Frequent exercise is perceived as a major behavioural determinant for improved life expectancy and a slower rate of ageing. There is little doubt that frequent exercise is beneficial for individuals’ well-being, and an active lifestyle reduces the risk for chronic diseases. However, it is still uncertain whether the rate of ageing decelerates in response to frequent and intense physical exercise. Our attempt is the first empirical study to show the application of a parametric frailty survival model to gain insights into the rate of ageing and mortality risk for Olympic athletes.

Our participants for this parametric frailty survival analysis were Polish athletes who had participated in the Olympic Games from 1924 to 2010. We assumed that these athletes were elite in their preferred sports expertise, and that they were engaged in frequent, if not intense, physical exercise. The earliest recorded year of birth was 1875, and the latest was in 1982; total N=2305; male=1828, female=477. For reliable estimates, mortality improvements by calendar events and birth cohort had to be taken into consideration to account for the advancements made in medicine and technology. After the consideration of mortality improvements and the statistical power for parametric survival analysis, we restricted our analysis to male athletes born from 1890 to 1959 (M=1273). For reliable estimates, we preassigned recruited athletes into two categorical cohorts: 1890-1919 (Cohort I); 1920-1959 (Cohort II).

Our findings suggest that Polish elite athletes in Cohort I born from 1890-1919 experienced a slower rate of ageing, and had a lower risk for mortality and a longer life-expectancy than the general population from the same birth cohort. It is very unlikely that these survival benefits were gained within a short observational time. Therefore, we argue that participation in frequent sports from young adulthood reduces mortality risk, increases life-expectancy and slows the rate of ageing. The age-specific mortality trajectories of Cohort I elite athletes also suggest frequent exercise can decelerate the rate of ageing by 1% with an achievement of threefold risk reduction in mortality. In comparison with those of the general population, the differences in energy expenditure, behavioural habits, body mass and sports expertise were likely to be the contributing factors to the higher variance in lifespan among elite athletes.

In Cohort II, the estimated rate of ageing is highly similar between elite athletes and the general population, which contradicts our estimates for Cohort I. This may be attributed to mortality improvements from year 1920 onwards in Poland. These mortality improvements have changed individuals’ susceptibilities for different causes of death, which has resulted in an increased variation in lifespan both in the general population and for elite athletes. Interestingly, the comparison of the rate of ageing of elite athletes in Cohort I and II shows a similar rate of ageing. Among the elite athletes, the estimates suggest that Cohort II individuals benefited from a 50% mortality risk reduction as compared with individuals born in Cohort I. The estimated overall mortality risk of the Polish general population is 29% lower in Cohort II than in I.

Buy Team America? – Article by Gary M. Galles

*****************************

Samuel Johnson once wrote that “patriotism is the last refuge of a scoundrel,” criticizing adverse policies and proposals falsely claimed to be based in patriotism. This has been most recently illustrated by the political furor over “made-in-China” Team USA uniforms. Many politicians asserted that it was un-American, with Senate Majority Leader Harry Reid saying those uniforms should be burned. Supposedly patriotic pressures to mandate “buying American” sprang up immediately, and Ralph Lauren quickly capitulated, promising to “go and sin no more.”

While some of the details of this flap are unusual, protectionism dressed up as patriotism follows a well-worn script.

Imports are found to cause some domestic harm. Given that those imports harm competing domestic producers, “Buy American” or some other version of protectionism is put forth as the patriotic response (with the producers seeking protection from superior competitors leading the patriotism bandwagon). The Team USA version simply exploits the Olympics’ peak in pro-American sentiment and symbolism to make the same case (though it makes no more sense than requiring that we grow our own coffee and bananas for our athletes).

The problem is that imports always harm competing domestic producers, so that the patriotism argument can always be used as political cover whenever any domestic producers get the government’s ear. And there are always politicians ready to listen.

One person who recognized the abuses and illogic of this approach was Leonard Read. In particular, his chapter “Buy American,” in Having My Way (1974), lays out a better way to approach the issue.

The admonition to “Buy American” has two diametrically opposed meanings. The first is its popular and mischievous meaning — shun goods produced in foreign countries. The second, and loftier meaning embodied in these words, is rarely mentioned or thought of — shun principles and practices alien to the American dream of limited government and personal freedom.

Producers who plead with consumers to “Buy American” are appealing to blind patriotism. Buy my product because it is made here; heed not its price or quality. This is sheer chauvinism. Suppose I were to urge your acceptance of my ideas, rather than those of Marx or Machiavelli, merely because of our differing nationalities. The absurdity of such an appeal is obvious: neither goods nor ideas are properly judged in this fashion; geographical origin has nothing to do with the matter.

Read points out that that the traditional use of “Buy American” is to justify some citizens beggaring their own neighbors, rather than something that advances any sensible interpretation of our general welfare. However, there is an interpretation that does advance our general welfare. Don’t buy (i.e., accept and make use of) actions that violate the American principle of freedom to choose your own productive associations, as long as you don’t violate the common, inalienable rights of others.

Read recognizes that whether a principle is true or not has nothing to do with where it comes from (i.e., ad hominem or “against-the-man” attacks do nothing to invalidate something that is true, although you wouldn’t know it from political rhetoric). As a result, he offers an excellent way to test whether some supposed general principle is valid — change “Buy USA” to “Buy Chinese” or “Buy Mexican,” and ask if Americans would accept the proposition as true based on their patriotism. If it is really a general principle, it is as valid for others in their dealings with us as their potential suppliers as it is for us in dealing with them as our potential suppliers, and the answer would not change. We would support others’ protectionism just as much as our own. But if it is really special pleading, rather than a general principle, people’s answers would change, as when people hypocritically attack other countries for their protectionism at the same time we defend ours as principled.

Read also recognized that the extent of protectionism is far vaster than most people recognize.

All obstacles to competition, be they foreign or domestic, are but variants of this theme.

The difference between a ban on buying a foreign country’s products and imposing tariffs, quotas, or any of a host of nontariff barriers is only one of degree. Whether it benefits or harms Americans does not change; only the degree of such benefit or harm. Similarly, change “Buy American” to “Buy Local,” as with locavore campaigns in agriculture, and the logic is equally invalid.

Such protectionism goes well beyond international trade, as well.

Change the wording to “Buy Union,” as with project labor agreements and prevailing (higher-than-competitive) wage laws, and the logic is the same. Union members are protected from the competition of other workers who would work for less. But that protection not only harms nonunion workers; it also harms customers, whose costs are increased.

Price controls are also protectionism. For example, a minimum wage protects other workers from competing with those who would be willing to work for less, but it harms both those denied their most productive employment and consumers.

The vast majority of antitrust cases are also forms of protectionism. They are not brought by consumers, who generally gain from the practices involved, but by outcompeted rivals who want to take away others’ advantages — advantages passed on to customers. Those outcompeted rivals don’t want potential customers to go elsewhere — and use antitrust to restrict consumers’ ability to access superior options.

A vast array of licensing schemes follows the same pattern. They hide behind masks of quality or safety but primarily keep new competitors out and keep those who would offer lower-quality–lower-price options some customers would prefer from doing so.

Leonard Read offers a powerful solution, powerfully illustrated by America’s own past.

Enough of this mischievous notion. Let us try instead to appreciate and “buy” the American ideal of freedom.

Ralph Waldo Emerson had this to say: “America is another name for opportunity. Our whole history appears like a last effort of divine Providence in behalf of the human race.”

As to the best in political economy, consider the Constitution of the United States. Regardless of its several flaws, no other nation’s charter has equaled it in an economic sense.

In what respect is this distinctively American? Here is the answer: “No state shall without the consent of the Congress, lay any imposts on imports and exports … “

In a nutshell, no tariffs, quotas, embargoes between the several states…the world has never known a free trade area as large as the U.S.A. when measured in value of goods and services produced and exchanged. Never perfectly free, but the nearest approximation to freedom!

In other words, the freedom to associate for productive purposes however and with whomever one chooses, because people were protected from many of the violations of that principle that governments have imposed throughout history, was the essence of the American miracle. And at its heart, as Thomas Jefferson wrote, was “the first principle of association, the guarantee to everyone the free exercise of his industry and the fruits acquired by it.”

Further, Read’s focus on America’s free internal trade offers a counterpoint to a frequent misinterpretation. Those who defend protectionism as a valid principle claim that it was the protectionism adopted by the United States in the form of tariffs that advanced our staggering early economic success. While it is true that import tariffs were imposed, and eventually dramatically raised (see the history of the “Tariff of Abominations” as an example), that was not the source of our success any more than hurdles — which slow running speeds — should be given credit for increasing running speeds because hurdlers are fast. The reality is that the positive impact of our massive internal free-trade zone and other constitutional restrictions on government interference far outweighed the negative impact of international-trade restrictions.

Read then addresses one particular common defense of protectionism: the “infant-industry” argument that free trade may be good in general, but that industries must be protected until they can grow to a scale where they can compete, which amounts to a claim that the benefits of freedom require restricting the freedom that generates them.

In reality, it is competition which protects “infant industries” — it protects them from stagnation and persuades them to grow.

In the absence of competition and freedom of transactions, producers stagnate. It is only when others are doing better that one attempts to overcome, to gain strength. Competition, combined with free exchange, makes strong giants out of weak infants — this is the password to economic opportunity and well-being — an American idea well worth buying.

Read recognized that from the perspective of consumers it is the competition that takes place without artificial assistance or restriction that expands their options the most. It does not matter whether competition leads to a foreign producer who offers better terms because of superior efficiencies or if that producer is American. So there is no reason to artificially nurture American infant industries (which often claim to be infants virtually forever), because it is the results of real superiority that benefit consumers, and artificially tilting the playing field only inhibits the process that best discovers and passes on the gains of such superiority.

Read next turns to another test that rejects the logic of protectionism. If we accepted protectionism in principle, we would be for it in all cases. But, as he notes, we are all free traders when it benefits us. In other words, we recognize that we gain from free trade, except when we are the one benefitted by special treatment — necessarily at others’ even greater costs — by those restrictions. We abandon our own revealed preference for freedom only when bribed by receiving some of what is essentially stolen from others.

Regardless of all the noisy arguments to the contrary, everyone known to me favors both competition and free trade. Name one who does not favor competition among those from whom he buys. Logically, then, how can one favor competition among millions of others and be against it for himself! This is irrationality, not disagreement.

Precisely the same can be said for free trade — domestic or foreign. Name one who would not welcome an order for his products from another country or county. Everyone favors exports. Imports? Favoring exports and objecting to imports is the same as favoring selling and objecting to being paid. This is an absurdity, not disagreement.

Leonard Read realized that the logic of protectionism is riddled with errors and that the practice of protectionism, in its myriad forms, is theft that impoverishes everyone except those bribed by the gains of their protected status and those whose political clout greases those transactions. It is a far cry from either liberty or justice for all. Read’s conclusion:

What then is meant by “Buy American” in its proper sense? Let willing exchange prevail among all people, locally and worldwide. Let each buyer or seller be guided by his own scale of values. Sell the American way and buy the American way — not as presently practiced, but as once prevailed and ought to be reinstituted. Keep ours the land of opportunity for everyone.

I’ve Got Olympic Fever – and the Only Cure is More Nationalism! – Article by Bradley Doucet

The New Renaissance Hat

******************************
Once again, the Olympics have come and gone. Some of the best athletes from around the world competed to see who could run, swim, row, dive, jump, kick, shoot, spike, spin, flip, and twist faster or higher or more artfully than their opponents. And that part of it was great. Well, some of it was dull as dirt, but some of it was genuinely thrilling and even beautiful.The part of it that I don’t get is where I’m supposed to cheer for the guys and gals who are “representing” Canada. I’m supposed to feel disappointed when these fine young men and women fail to live up to expectations, and I’m supposed to be happy, even proud, when they make it to the podium. And people from other nations are supposed to feel these emotions for the athletes “representing” them. Well, not only do I not feel anything special for Canadian athletes, but I would go so far as to say that such seemingly innocuous nationalistic sentiments are a big part of what’s wrong with the world.Nationalism by Any Other Name

For my money, foul-mouthed stand-up comedian Doug Stanhope put it best: “Nationalism does nothing but teach you how to hate people that you never met, and all of a sudden you take pride in accomplishments you had no part in whatsoever…” Now granted, the Olympics are not so big on the hate. But why should I, simply because I’m Canadian, take pride in the fact that Canada hauled in 18 medals? And should I feel a little less proud because only one of them was a gold? Of course, strictly speaking, “Canada” did not win 18 medals. Rather, Canadian athletes won 18 medals. But why should “we” care one way or the other, much less feel vicarious pride? We didn’t build that.

To be clear, I’m not against sporting events per se. I actually like sports, both playing them and watching them. I like watching basketball and American football, and I even root for certain teams (the Celtics and the Patriots). I enjoy watching my fellow human beings perform incredible feats of strength and agility, and struggle to summon extra energy or settle frazzled nerves. Watching tennis star Na Li rally from a 1-5 deficit in the deciding third set of her semi-finals match at the Rogers Cup in Montreal this weekend to win six straight games and take it 7-5 was both exciting and inspiring. I like the way Na Li plays—I refuse on principle to place her family name first, regardless of what is done in her nation—and she’s got a pretty quick wit, too, judging from the times I’ve heard her speak. Why should I give a damn what her nationality is?

I did watch some Olympic tennis, including the record-breaking third set of the match between Milos Raonic and Jo-Wilfried Tsonga that took 48 service games to decide. I was impressed that Raonic could give Tsonga such a run for his money, but the fact that we are countrymen was the furthest thing from my mind. In fact, I was happy that Tsonga finally won the match. I enjoy his style of play, and he’s actually my favourite player on the men’s tour at the moment. Different nationality, different mother tongue, different skin colour? I literally could not care less.

The Hosts with the Most

What about the host country? In an article in the Globe and Mail, Doug Saunders wrote of the “mood of national euphoria” in England following the closing ceremonies, and of the “ineffable value of having organized a very large, very happy event with virtually no flaws, and having looked very good before the world—something that Britain once took for granted, and is likely to enjoy remembering for some time.” The implication is that Britain should feel proud of the great job it did hosting the Games.

But again, did “Britain” host the Games? Did “the British people” host the Games? No. Some small subset of specific individuals organized the event, for better or for worse. Why would every Brit deserve credit for that? Now, British taxpayers did foot the bill, whether they wanted to or not. And what a bill it was, totalling some $14.5 billion. (You can forget about any economic stimulus from hosting the Games, by the way. As Saunders tells it, the prospect of daily Olympic crowds of 100,000 kept at least 300,000 non-Olympic tourists away.)

Similarly, as a Canadian taxpayer, I financed some tiny fraction of the training of the Canadian athletes participating at these Games, who were subsidized to the tune of $96 million over the last four years. (For those of you keeping track at home, that’s five million and change per Canadian medal.) The thing is, paying taxes is not really something a person does; it’s something that is done to a person. I cannot therefore reasonably feel proud of what is done with those dollars once they are taken out of my account against my will, and neither should the British taxpayer.

For Love of Country

On a trip to Ottawa a few years ago, I saw a bumper sticker that captured my feelings about Canada: “I love my country, but I’m afraid of my government.” Canada is a fine place with many fine people who continue to enjoy the echoes of a strong classical liberal tradition. But those “representing” us (there’s that word again) in the halls of power are not generally speaking the finest of those fine people.

For one thing, they all seem to be nationalists of one stripe or another. I suppose it wasn’t surprising to see Pauline Marois, leader of the separatist Parti Québécois, celebrate the fact that Canada’s first four medals were won by Quebecers. Rather more disappointing was how all three major provincial party leaders were competing to oppose the purchase of homegrown Rona by US rival Lowe’s. The race for gold in the “economic nationalism” event was too close to call.

Someone is surely going to argue that the Olympics are all about the nations of the world coming together in friendship. Well first of all, at the risk of beating a dead dressage horse, “nations” cannot be friends. Only people can be friends, and some of the Olympians probably made some new connections. But do the Olympics help people from different parts of the world adopt friendlier attitudes toward one another? An American basketball team packed with NBA superstars rolling roughshod over every other team tells a different tale, as does the rash of below-the-belt punching in the quest for basketball gold. And how about those bad calls against the Canadian women’s soccer team, denying them a chance to play for gold? That really promotes friendly international relations.

One parting shot: I’ll take the human achievement of the Mars landing over the nationalistic achievements of the Olympics any day. And although again, the taxpayer funds used to pay for it rub me the wrong way, at $2.5 billion, the price tag was roughly 1/6 as large as the Olympic tab.

Some kind of reverence for imaginary lines on a map seems to be deeply ingrained in most people, but to me, honestly, winning a medal “for your country” is only slightly less creepy than winning one for your Dear Leader. I prefer the humanist sentiment of elation of one Western writer (I’ve tried in vain to relocate his name) who, upon seeing the Great Wall of China for the first time, exclaimed, “My people built that.” Human beings can do great things, which should be a source of encouragement and inspiration for us all, regardless of the colours of our passports.
