Helsinki just went a full year without a single traffic death The capital city is Finnish’ed with car-related fatalities.

β€œHelsinki hasn’t registered a single traffic-related fatality in the past year…Citing data that shows the risk of pedestrian fatality is cut in half by reducing a car’s speed from 40 to 30km/hr, city officials imposed the lower limit in most of Helsinki’s residential areas and city center in 2021.”

Who said this? Neither AI nor search engines have gotten anything specific.

EPA to repeal its own conclusion that greenhouse gases warm the planet and threaten health Known as the endangerment finding, the decision is the legal framework that allows the EPA to regulate emissions. Its reversal could upend many climate change policies.

Well, this is fun. Do you like breathing clean air?

Interesting.

Serious inquiry: what does blocking do for you? Reduce inflammation? Increase happiness? Other?

(This is curiosity driven from my perspective)

Just a friendly reminder as we go into the holidays:

Folks don't have to explain to you why they don't drink.

If you offer them a drink and they decline, don't ask them why. It's not your business.

Just offer them something without alcohol to drink instead. And move on.
