Hair cells do not grow back, and the safe exposure time halves with every three decibels. At 100 dBA – earbuds near maximum – the daily allowance is fifteen minutes; venues average 104 to 112 dB. The exposure table, the evidence on temporary threshold shift, and the protection actually worth buying.
Seventy-six per cent of identity theft involves an account you already have, and a credit freeze does not touch that category. What a freeze actually blocks, how fast the bureaus must act by law, the difference between a freeze, a lock and a fraud alert, and what covers the other three quarters.
A magnitude 5.9 near Tokyo in August 2026 injured 37 people and knocked down no buildings — almost all of them hurt by furniture, doors and falls. In Northridge, deaths came from collapse but hospitalisations came from falling objects. Here is what the injury data says about securing a room, why the “Triangle of Life” is wrong, and the eight fixes that matter — four of which are free.
Most homeowners policies exclude flood entirely — and 29% of US flood claims came from outside the designated high-risk zones, where nobody is told they need it. The gaps that show up at claim time, and the two-hour job that fixes most of them.
Between 20 and 25% of epinephrine administrations in schools are to children with no known allergy — a first reaction, with no care plan. And the delay that turns a frightening afternoon into a fatal one is usually an antihistamine reached for first.
In 2024 the WHO dropped the droplet-versus-airborne distinction that underpinned decades of advice. Exhaled particles behave like smoke, not falling cannonballs — which moves ventilation to the top of the list and surface cleaning near the bottom.
The 2024 Lancet Commission put 45% of dementia cases down to 14 modifiable risk factors. Two were added that year — midlife cholesterol and untreated vision loss. Almost none of the list is something you buy, and no supplement appears on it at all.
Over 400 Americans a year die from carbon monoxide unrelated to fires. The symptoms impersonate flu — but CO causes no fever, affects everyone in the building at once, and eases when you leave the house. What actually distinguishes them.
The EPA gave water systems until 2034 to replace up to nine million lead service lines. How to find out in one minute whether yours is one of them, which filter specification actually matters, and why boiling makes lead worse rather than better.
The FBI logged its first AI-fraud category in 2025: 22,364 complaints and $893 million. A few seconds of public audio is enough to clone a voice. The scam has one shape, one tell, and one free defence that defeats all of it.
