An extended resilience intervention in at age 6 produces significant and meaningful decreases in all-cause mortality, chronic disease, and dementia rates, while increasing accumulated wealth, subjective well-being, and walking speed by age 65; but every persona tells a different story.

The Trump administration gutting so much fundamental research is going to set the U.S. back so much in ways that will shock historians in the future.
The current deliberate tanking of the economy will seem mild in comparison.

Public smoking bans just got in under the wire, too. Younger folks might not realize how rare they used to be and how hard they were to enact.
it is MIRACULOUS that we got rid of lead paint and asbestos when we did. if we had tried that today, there would be people whining about how we're restricting their rights.
Bring back residential-use lead paint, you cowards.
