The unbalanced, short-wavelength-heavy spectrum of common LED lights, which lacks counteracting long-wavelength red light, may cause systemic mitochondrial dysfunction. Some scientists believe this is a major public health issue with a potential impact comparable to that of asbestos.

Most people use 10-20 times the recommended pea-sized amount of toothpaste, leading to a significant overdose of fluoride. This is concerning because fluoride is classified as a neurotoxin linked to lower IQ in children and thyroid dysfunction. It's absorbed systemically through the mouth's lining, even without swallowing.

Standard metrics like the Air Quality Index (AQI) are abstract and fail to motivate change. Economist Michael Greenstone created the Air Quality Life Index (AQLI), which translates pollution into a tangible, personal metric—years of life expectancy lost—making the data hard to ignore and spurring action.

During the COVID pandemic, some people drank bleach because our brains are wired to despise uncertainty. In the absence of clear answers, we gravitate towards any promised solution, however dangerous, because taking action provides a false sense of control.

AI companies minimizing existential risk mirrors historical examples like the tobacco and leaded gasoline industries. Immense, long-term public harm was knowingly caused for comparatively small corporate gains, enabled by powerful self-deception and rationalization.

Contrary to widespread belief, generic drugs are not always identical to brand-name versions. Experts estimate a 13% failure rate, meaning they may lack potency, contain contaminants like arsenic, or have faulty delivery mechanisms, posing significant safety risks.

Other scientific fields operate under a "precautionary principle," avoiding experiments with even a small chance of catastrophic outcomes (e.g., creating dangerous new lifeforms). The AI industry, however, proceeds with what Bengio calls "crazy risks," ignoring this fundamental safety doctrine.

Thermal paper receipts are coated with unbound Bisphenol A (BPA), an endocrine disruptor. Using hand sanitizer or lotion, which many people do for cleanliness, dramatically increases the skin's absorption rate of this chemical. This poses a significant health risk for cashiers and frequent shoppers.

Thermal paper receipts are covered in BPA, an endocrine disruptor. Handling them transfers it to your skin, but using lotions or hand sanitizers increases its absorption into your bloodstream a hundredfold. This is a critical risk for cashiers and frequent shoppers.
