🚨 do you understand what New York City just accidentally admitted..
NYC spent $81,705 per homeless person last year.. the median American household earned $81,228.. the government spent MORE to keep someone homeless than most families earned to keep themselves housed..
that $81,705 isn't going to the homeless person.. it's going to the system around them.. shelters, administrators, case managers, contracts, overhead.. the industry that manages homelessness.. not the end of it..
if NYC gave every homeless person that money directly.. they could afford nearly 2 years of rent.. most of them wouldn't be homeless anymore..
instead the money goes to the system.. the system keeps running.. the homelessness stays.. and every year they ask for more funding to manage the problem that the funding was supposed to solve..
the homeless are worth $81,705 a year to the system..
they're worth nothing to it solved..

The current physical activity guidelines undervalue vigorous activity.
Vigorous activity may be 4–9× more potent than moderate activity for reducing all-cause mortality, cardiovascular disease, diabetes, and cancer risk.
The exercise guidelines assume a 2:1 ratio between moderate- and vigorous-intensity activity: two minutes of moderate activity equals one minute of vigorous. That's why the recommendations are 150–300 minutes of moderate or 75–150 minutes of vigorous activity each week.
But new data suggest that ratio is wrong.
In this brand-new journal-club episode, Brady Holmer (@Brady_H) and I unpack a groundbreaking study that should change how we think about activity for disease prevention.
The research identified that 1 minute of vigorous activity is roughly equivalent to 4–9 minutes of moderate activity, and 53–94 minutes of light activity, for disease risk reduction. It also shows a clear dose-response for vigorous activity that’s much weaker for moderate activity and barely detectable for light activity.
We also do a deep dive into why vigorous activity is so powerful, the underlying mechanisms, and discuss practical takeaways, including how even very brief bouts of vigorous movement (think “exercise snacks”) can produce meaningful health benefits.

As vehicles continue to improve in fuel economy and EVs become more common, a direct user fee on each mile driven, a vehicle miles traveled tax (VMT), would be a better long-term solution to funding highway projects in the future.

I just, for the first time, returned a new Samsung product. The new Watch8 is not an upgrade over the Watch7. Samsung, please do better. I can't say I'm not a little disappointed in my S25 ultra either. The "AI" features were not as much of an upgrade as I thought they would be.
