And sure, this study cannot disentangle whether the long-term drop in life expectancy is due to COVID itself or to any knock-on effects. Be that as it may, the "life expectancy will return to where it was" mantra was short-sighted regardless.

Many believed that reductions in life expectancy brought about by COVID would be temporary. This struck me as naive. COVID was a new, poorly understood disease with unknown long-term consequences. Six years later, all the data suggest that such optimism was unjustified.

Sunrise and sunset are different things than it being light and dark. They used to teach that in school.

Your statement was that kids go home in the dark at present. They don't.

Goalpost shifting aside, I don't see how your response changes things for the better. Under standard time, at 8 am in December, there is already natural light. When that becomes the equivalent of 7 am, there won't be.

I suspect that a good half of the support for permanent DST comes from people that do not understand how the distribution of daylight will actually change. That 90% approval (from a question in which permanent standard time was not an option) will tank hard in the winter of 2027.

And a darker morning commute is exactly what will now happen for a good four months of the year.

In Western BC, Permanent Daylight Savings Time means that kids will now go to school in the dark in winter.

The issue is that they don't go home from school in the dark with Standard Time. School is 9-3, so under Standard Time there's daylight at both ends. Under Daylight Time there isn't, and the morning walk in the dark will take place at the same time of the morning commute. Dangerous all around.

Would anybody like to read one of my long threads about a 2.5bn year old rock, bacteria that could produce oxygen but not consume it, and tank production in wwii

I am delighted that this great conversation with Ran Abramitzky and Leah Boustan has posted. Their extraordinary work on intergenerational mobility and immigrants speaks to essential dimensions of the extent of equality of opportunity and of the process of assimilation.

Everyone working in development economics should read this chapter.

They provide evidence that what works in development is less about finding universally good levers and more about designing interventions compatible with locally embedded social structures.

Fond memories! They have the entire Doria family archive at the university. It was donated by Giorgio Doria, noted economic historian and descendant of the famous Dorias of old.

Until last year, I used to feed my exam questions to ChatGPT, paste them into the actual exam, and ask students to grade the answers. ChatGPT used to get scores of 20-40% on my 3rd year econ history exam. These days it routinely hits 80%, provided you feed it the reading list first.
