Health Essay
Shut your windows against the haze? You still breathe it, and a 302-worker study says you work slower.
Fires in Sumatra and Kalimantan pushed central Singapore to PSI 105. A 302-worker study found indoor PM2.5 slows desk work, and NEA’s purifier rule is a sum you can do tonight.

Health Essay
AI use volume did not predict the damage. What 1,032 students handed the model did.
Two kinds of AI reliance were measured separately in 1,032 Chinese undergraduates. Handing the model the labour barely moved the needle; handing it the judgement moved it three and a half times as far.

Health Essay
Nineteen of 51 longevity interventions lowered an epigenetic clock. Five raised it.
A harmonised database of 51 intervention studies grades the epigenetic clocks against each other, and the grading lands awkwardly on the biological age panel you are being sold.

Health Essay
Britain’s sugar ration ended in 1953. Those babies have 69% less liver cancer.
The end of British sugar rationing handed researchers 64,761 people and a two-year window, and the finding that lasts is what that cohort was still eating at fifty.

Health Essay
Fermented food moved 19 inflammatory markers in 10 weeks. Fibre moved none.
A Stanford trial got a measurable immune result out of the supermarket aisle, while US$706 million went into reprogramming rounds that have not reached a clinic.

Health Essay
A breast-cancer drug approved in 2015 cut frailty in old mice. Palbociclib’s asset is its 11 years of side-effect data.
Palbociclib and an anti-RANKL antibody both posted ageing results in one August week, and the strongest thing either has going is a decade of human safety filings.

Health Essay
Job insecurity raises coronary risk 19 percent. Your runway is the same exposure.
Uncertainty is metabolically expensive, and the brain bills the body. What the founders holding an undated question are actually paying.

Health Essay
NUS’s Dean Ho fasted 20 hours a day for a year. Resting heart rate fell 19 bpm.
DELTA put his estimated biological age at 31.8 against a chronological 45. The authors say that number lacks external validation, and the two markers underneath it do not.

Health Essay
Metformin, DCA and low-dose navitoclax extended old mice’s survival by 41.7 percent.
A UC Berkeley combination called DMA cleared senescent cells by starving them of ATP, and two of its three components already sit on a pharmacy shelf.

Health Essay
A Nature Aging screen flagged 14 approved drugs as pro-longevity, and 14 more that may do the reverse
A network-medicine screen out of Northeastern and Harvard put 6,442 existing compounds against the genetics of aging, and the half of the result that will never be marketed is the half worth reading.

Health Essay
NMN has no human lifespan data. Three of 18 Singapore bottles held none.
The lab that measured what Singapore’s longevity supplements actually contain also published the year’s largest read on physical activity and biological age, and the two papers point in opposite directions.

Health Essay
Three hours a week erased half of muscle ageing’s molecular signature
A Nature Aging cohort found 55.9 percent of the age-related upregulation in trained older muscle absent, and named the genes that training never touched.

Health Essay
Semaglutide slowed four epigenetic clocks in a randomised trial, and left a fifth unmoved
A 32-week randomised trial moved DunedinPACE, PhenoAge and two GrimAge clocks on weekly semaglutide; the Intrinsic Capacity clock, built to track how well a body still works, did not shift.

Health Essay
Burnout as a pricing problem (n=1, anecdotal, and the mechanism is still worth reading)
The WHO’s three burnout dimensions describe a relationship to the work, not a quantity of it. One Singapore operator’s decade is a clean, if uncontrolled, illustration.

Health Essay
The highest-return longevity move is free (and beats the S$18,000 reset)
A 30-year Harvard study of 147,374 health professionals found strength training’s longevity benefit plateaus fast, which reframes the five- and six-figure ‘biological reset’ packages Singapore’s longevity clinics now sell founders.
-
Health Essay
The mice ate more and lost fat. The lesson everyone will buy is the wrong one
A USC lab fed old mice a low-protein, plant-and-fish diet with just enough methionine; they ate more, carried less fat, and grew less frail, and the honest read points back at the meal the molecule keeps getting sold as.

Health Essay
Social isolation raises death risk 29 percent. The fix is a room of people.
The peptide-and-cold-plunge internet skips the intervention with the hardest evidence behind it, because a room full of people on a Tuesday cannot be turned into a product.

Health Essay
Singapore bet S$350m on longevity. The scalable part is the coaching call.
The 2026 senolytics results are real and early; the wealth in a fast-ageing Singapore accrues to whoever gets a 55-year-old to comply.
-
Health Essay
The most-studied longevity drug is a cheap 1970s generic
Rapamycin, a 1970s transplant generic, has more human data behind it than any longevity compound, and the trial authors still call the case unestablished.

Health Essay
Life Biosciences put age reversal in a human eye. Results are five years out.
Life Biosciences has put the first partial-reprogramming therapy into a human eye. Strip away the science fiction and what is left is a lesson about the kind of bet you make when you cannot undo it and cannot check the result for years.

Health Essay
NewLimit raised US$435m to reverse cell age. Sleep is the asset you own today.
NewLimit just raised US$435 million to reverse cell age in a lab. The only longevity asset an operator actually controls today is still sleep, training, and what time the kitchen closes.

Health Essay
Thymic health predicts adult mortality. AI now reads it from routine CT scans.
Hugo Aerts’s group scored 28,500 CT scans through an AI model that reads thymic involution; the top-quintile gap was 50 percent on all-cause mortality, 63 percent on cardiovascular death, 36 percent on lung-cancer incidence. Whether any intervention moves the marker is the unanswered question.

Health Field note
ApoB moves first. Biological age moves less than the clinics claim.
Three Singapore principals, ages 47 to 53, six months on structured longevity protocols, paying $38,000 to $94,000 a year. The biomarkers that moved are below. The ones the clinics oversold are below.
