The composition and expiry rules came from one 2003 appendix, and its author regrets it. What actually takes over accounts is reuse, infostealers and phishable codes.
Virtually all crowd deaths are compressive asphyxia, not trampling, and the word stampede points the blame in the wrong direction. The density ladder, the forces involved, what the Itaewon and Karur investigations found, and the one threshold worth acting on: when you are touched on all four sides, leave.
While you are saving, only the average return matters. The moment you start withdrawing, the order matters enormously – and a bad first decade does permanent damage. Where the 4% rule came from, what Morningstar puts the number at now, and why planning to average life expectancy is a coin flip.
A randomised trial found that using a regular adult cuff on someone who needs an extra-large one overestimates systolic pressure by about 20 mmHg – enough to turn 125/79 into 144/87 on the same arm. What the WHO numbers say about the 600 million who do not know, what SPRINT actually showed, and how to get a reading worth acting on.
A survey of 422 incarcerated burglars found occupancy, police proximity and a dog outranked alarms and cameras, that only about 12% picked a lock, and that fewer than a third cared about lighting or neighbourhood watch signs. What that means for where the money is worth spending.
Embers are the leading cause of home ignition in wildfire, and they arrive miles ahead of the fire. An ember-resistant buffer halves a home ignition risk, and clearing perimeter vegetation nearly doubles survival odds. Why the first five feet matter more than the next ninety-five, and which measures have evidence behind them.
The FBI warned in May 2025 that end-of-life home routers are being taken over for criminal proxy networks, using malware that needs no password. What attackers actually want is your residential IP address. The eight settings that matter, why the guest network is the highest-value free change, and the backup rule that is the only answer to ransomware.
Children cannot reliably detect a vehicle approaching above 20 mph – a developmental limit, not carelessness. What that means for the school run, the 44% injury reduction Safe Routes to School produced in New York, and why nearly two thirds of school-bus-related child deaths happen outside the bus.
Four known places-and-times identify 95% of people in an anonymised mobility dataset, and coarsening the data barely helps. How real-time bidding broadcasts your location to bidders who keep it even when they lose, what the FTC found inside Mobilewalla and X-Mode, and which defences actually work – including the deletion platform California switched on this month.
More than three quarters of US pedestrian deaths happen after dark, and fatal night crashes rose 84% in thirteen years. What the IIHS found about tall, flat vehicle fronts, why night-time autobrake still struggles, and the vision research showing the same reflective material works two to five times better on your ankles than on your chest.
