We don't really get older but on average we do

      Congratulations young man.

      I see in the first graph that in the first corona year (2020) the average age (AL) at death was higher than in 2019 and fell sharply in 2021 when the shots were given en masse, especially to the elderly.
      Now you can reason that this is (largely) because at that time it was mainly (stick) elderly people who died of corona. But if I see the following statement: age at death 80+, then the difference between 2019, 2020 and 2022 is minimal.
      Can you give a plausible explanation for this?

        The group 65-80, and that the same (stick) elderly would also have died without corona. Seems plausible to me.

    Congratulations on this new, sharp, light-hearted and at the same time insightful piece.... And of course also with your birthday 🙂

    Congratulations. 1959 was an exceptional year of construction. Coincidentally, I'm out of 🙂 that too
    It's not about how old you get, but how you get old.
    And that may be as healthy and free as desirable as I want (not possible because that is becoming more limited by the day) Seize the day.

    Which number is better

    1. Average life expectancy?
    2. Or average age at death?

    Ad 1 has the advantage that it tries to take into account that we seem to be getting older, but has the disadvantage that a model has to be used to calculate it.
    Ad 2 has the advantage that they are real numbers (nothing modeled), but the disadvantage that someone who dies as an 87-year-old in 2020, maybe if he was born 40 years later, would still be alive in 2060 (due to all those fantastic medical advances, and clean air and so on...)

    Personally, I tend to find ad2 more reliable than ad1.

    What ad1 does not take into account is that the average age is not only increasing because of clean air and so on, but is also increasing because there is less and less infant mortality (see e.g. https://www.cbs.nl/nl-nl/cijfers/detail/37979ned)

    In 1950, 75,929 Dutch people died, of which 6,126 were infants (8.0% of the total), while in 2023, 169,521 Dutch people died with an infant mortality rate of 598 (0.4%).

    To follow now, beer mat statistics...

    Suppose that the average age at which someone dies (and who has passed the age of infant) is 88 years in year out, but you don't include that in your averages (because you count from birth), then the average age of death for the 1950 cohort is (88*92)/100=81 years and for the 2023 cohort (88*99.6)/100=87.6 years

    In other words: since 1950, almost 7 years of life expectancy has increased if you don't take into account infant mortality.

    Now I get from your graph 4 that the average age of death for the 1950 cohort is about 72 years, and for the 2023 cohort is about 82 years. In other words, a 10-year increase in life expectancy of which (according to my beer mat statistics) 7 years is explained because fewer children die as infants in 2023 than in 1950. The remaining 3 years will then (maybe) be due to better care (perhaps something: thrombolytics for cerebral infarction does something, so do pacemakers, antibiotics I still believe in, blood pressure reducers can be useful, anesthetics in operations are also becoming safer and laporoscopic operations are also safer than open surgery, etc), cleaner air (would it??) or (seems to me also a very likely: the drastic decrease in the number of smokers (in the 50s more than 90% of the population smoked, now 'only' 25%).

    What I want to say is that our increased life expectancy is largely explained by decreased infant mortality, which I have dressed up above with numbers, with the help of a... coaster!

    Now it's time to do other things...

    Congratulations on your King's Day, Anton!

      I also made a graph of 1+ but the difference on this time scale (from 2010) was so small that I chose All Ages.

    Oud worden is een begrip waar we eens naar moeten kijken omdat het je kan overkomen.
    Stel je wordt 100 en ligt de laatste 30 jaren van je leven te staren naar een plafond.
    Of je wordt 90 en in de laatste week voel je iets van een niet pluis gevoel.

    Vang dat maar eens in een grafiek!

      Dan moet je zoeken op QALY. Daarmee wordt e.e.a omgerekend naar een eenheidscijfer.
