While specific, medically-approved red light therapies show promise for treating conditions like macular degeneration, consumer-grade devices bought online are often unstandardized. They can emit the wrong energy levels, potentially burning the retina and causing irreversible harm.

Applying cold, like cucumbers, constricts blood vessels to reduce swelling. However, prolonged application beyond 15 minutes can trigger a paradoxical effect, causing blood vessels to dilate and leading to increased inflammation, worsening the initial problem.
The next frontier for Neuralink is "blindsight," restoring vision by stimulating the brain. The primary design challenge isn't just technical; it's creating a useful visual representation with very few "pixels" of neural stimulation. The problem is akin to designing a legible, life-like image using Atari-level graphics.
Long-term, consistent use of ketone esters based on 1,3-butanediol, a very common formulation, may lead to liver toxicity. This risk exists even at doses that are not considered excessively high, such as those used by endurance athletes or in protocols for Alzheimer's.
The Orphan Drug Act successfully incentivized R&D for rare diseases. A similar policy framework is needed for common, age-related diseases. Despite their massive potential markets, these indications suffer from extremely high failure rates and costs. A new incentive structure could de-risk development and align commercial goals with the enormous societal need for longevity.
Research consistently shows that blue light from digital devices lacks the power to increase the risk of aging eye diseases or contribute to eye strain. The relief some users feel from blue light glasses may be a placebo effect or due to their anti-glare coating, not blue light filtration.
Modern ethical boards make certain human studies, like extended fasting, nearly impossible to conduct. This creates an opportunity to revisit older, pre-regulatory research from places like the Soviet Union. While the proposed mechanisms may be outdated, the raw data could unlock valuable modern therapeutic approaches.
Instead of replacing experts, AI can reformat their advice. It can take a doctor's diagnosis and transform it into a digestible, day-by-day plan tailored to a user's specific goals and timeline, making complex medical guidance easier to follow.
To significantly slow the progression of age-related macular degeneration, a leading cause of blindness, a surprisingly modest diet change is effective. Consuming just two servings of oily fish and 2.7 servings of green leafy vegetables per week reduces the risk of the disease advancing by 41%.
Staring directly at the sun, a practice some promote for spiritual or health benefits, is extremely dangerous. The eye's lens magnifies sunlight, focusing intense energy on the retina and causing solar retinopathy—permanent burn holes that create irreversible blind spots.
There are 12 million major diagnostic mistakes per year in the U.S., resulting in 800,000 deaths or disabilities. Cardiologist Eric Topol frames this as a massive, under-acknowledged systemic crisis that the medical community fails to adequately address, rather than a series of isolated incidents.
