Most popular advice is either outdated folk belief or commercial advertising. Here are a few counter-intuitive realities verified across clinical cohorts and statutory law:
- 🚗 Cold meds impair driving worse than alcohol: Taking common OTC allergy or cold medicine containing diphenhydramine degrades steering control and brake response time more severely than driving legally drunk at 0.10% blood alcohol. (Ch 34, Rule 12)
- 🛁 Hot baths & saunas after drinking can be fatal: Alcohol dilates peripheral vessels; pairing it with hot water causes acute blood pressure drops and fainting. This is the #1 domestic cause of adult bathtub drowning deaths. (Ch 22, Rule 11)
- 🧂 A $1 kitchen swap for 12% lower mortality: Switching normal table salt to a potassium-enriched blend reduced stroke by 14% and all-cause death by 12% in a randomized trial of 20,995 people—for pennies a month with zero extra effort. (Ch 02, Rule 9)
- 👶 Baby walkers delay independent walking: Wheeled infant walkers prevent crucial balance reflexes, cause over 230,000 emergency hospital visits, and have been banned by law in Canada since 2004. (Ch 20, Rule 15)
- 💼 Unsigned job contract? Demand double wages: If an employer delays signing your written labor contract past 30 days of starting work, statutory law entitles you to claim double monthly wages for up to 11 months. (Ch 19, Rule 20)
- 🏥 Hospital bill audits save thousands: Requesting daily itemized inpatient bill statements before discharge and auditing billing codes routinely uncovers billing errors and cuts self-pay expenses by 20% to 50%. (Ch 24, Rule 15)
- 💊 The supplement illusion: Multivitamins and regular fish oil capsules produce 0% reduction in all-cause mortality or heart disease in massive meta-analyses, while antioxidant overdoses (beta-carotene, vitamin E) slightly increase mortality. (Ch 06, Rules 1–4)
- 💳 Lending your bank card is a felony: Even if you make zero profit, letting an acquaintance use your bank card or transfer funds through your account constitutes criminal aiding of telecom fraud, carrying up to 3 years imprisonment. (Ch 09, Rule 5)

Every single rule in this repository adheres to a rigorous, verifiable template:
### 9. Switch household salt to low‑sodium (potassium‑rich) salt
<!-- Cost Tag: Money=Low Time=Low Willpower=No Benefit=High Metric=Mortality -->
- Cost: Slightly more expensive than regular salt. Bought during normal grocery shopping; no extra daily time needed. No noticeable taste difference.
- In plain terms: In a 20,000-person study, swapping regular salt for potassium-enriched salt cut stroke risk by 14% and death by 12% over 5 years. Because people were randomly assigned to groups, this evidence is much stronger than ordinary survey data.
- Benefit: In a cluster-randomized trial of 20,995 high-risk individuals followed for 4.74 years, the salt substitute group had a 12% lower risk of death from any cause (RR 0.88), a 14% lower stroke risk (RR 0.86), and a 13% lower risk of major cardiovascular events (RR 0.87).
- Evidence grade: A
- Sources: Neal B et al. (2021). Effect of Salt Substitution on Cardiovascular Events and Death. N Engl J Monte. https://doi.org/10.1056/NEJMoa2105675
- Notes: Individuals with severe chronic kidney disease or taking potassium-sparing medications should consult their physician first due to hyperkalemia risks.The manual is divided into 34 modular chapters under book/. You can read them directly here on GitHub or through the Interactive Web Reader.

Every recommendation is classified by the rigor of its underlying source:
| Grade | Scientific Standard |
|---|---|
| A | Quantified outcomes from comprehensive meta-analyses, large-scale multi-year prospective cohorts, or randomized controlled trials (RCTs) with concrete effect sizes. |
| B | Supported by peer-reviewed literature, but based on smaller cohorts, observational associations, or lacking multi-center replication. |
| C | Authoritative statutory frameworks, government agency consensus, or clinical heuristics without direct epidemiological trials. |
Across all 767 rules: Grade A: 495 | Grade B: 213 | Grade C: 59, with 80 rules noted for controversy. Controversial rules transparently outline counter-arguments in their Notes field.
Evidence tells you if something is true; ROI tells you whether it is worth your time and money:
| Dimension | Options | Description |
|---|---|---|
| Primary Metric | Lifespan / Wealth / Time & Energy / Freedom | The exact finite resource protected. |
| Benefit Size | High / Medium / Low | Evaluated objectively against pre-set benchmarks (e.g., mortality drop >= 20% is High; thousands saved is High; avoiding criminal liability is High). |
| ROI Ratio | Very High / High / Moderate | High benefit with zero/negligible cost = Very High; High benefit with low cost = High; all others = Moderate. |
Across all 767 rules: Very High: 122 (16%) | High: 344 (45%) | Moderate: 301 (39%).

| Term | Empirical Definition |
|---|---|
| All-Cause Mortality (ACM) | The proportion of individuals in a population who die over a specified time window, regardless of cause. Used throughout this book as the benchmark for genuine lifespan extension. |
| Hazard Ratio (HR) | The rate at which events (death, disease onset) occur in the exposed group divided by the rate in the unexposed group over time. An HR of 0.87 represents a 13% reduction in risk; an HR of 1.21 represents a 21% increase. |
| Relative Risk (RR) | The ratio of the probability of an outcome occurring in an exposed group versus an unexposed group. Interpreted identically to HR. |
| Odds Ratio (OR) | The ratio of the odds of an event occurring in one group compared to another. Closely approximates RR for rare events, but tends to exaggerate relative differences when events are common. |
| Incidence Rate Ratio (IRR) | The ratio of new disease cases per person-time in one group compared to another. |
| Rate Ratio (RaR) | The ratio of cumulative event occurrences (e.g., number of falls) rather than the number of unique individuals affected. |
| Standardized Mortality Ratio (SMR) | The ratio of observed deaths in a study population to expected deaths in the general population of identical age. An SMR of 5.86 indicates a mortality rate 5.86 times higher than peers. |
| Absolute Risk Difference | The simple arithmetic difference in event probability between two groups (e.g., 3 fewer deaths per 1,000 individuals), capturing actual clinical impact better than relative ratios alone. |
| 95% Confidence Interval (95% CI) | The range of values within which the true population parameter is estimated to lie with 95% certainty. If the interval for a ratio crosses 1.0 (or 0 for differences), the finding is not statistically significant. |
| Randomized Controlled Trial (RCT) | A study design in which participants are randomly allocated to an intervention or control group, providing the gold standard for establishing causal inference. |
| Meta-Analysis | A statistical synthesis combining quantitative results from multiple independent scientific studies to determine a pooled overall effect size. |
| Prospective Cohort Study | An observational study tracking a well-defined group of individuals over decades to measure how exposures correlate with long-term clinical endpoints. |
| Observational Study | Research where investigators observe participants without intervening. Prone to confounding and reverse causality. |
| Confounding | An external distortion where an unmeasured third variable influences both the exposure and outcome, creating a false illusion of direct causality. |
| Reverse Causality | An error in causal direction where the outcome inadvertently causes the exposure (e.g., serious illness leading to extended bed rest, rather than excess sleep causing illness). |
| Effect Size (Cohen's d, Hedges' g) | Standardized measure of the difference between two means: 0.2 indicates small, 0.5 moderate, and 0.8 large. |
| Correlation Coefficient (r) | Metric measuring the strength of linear association between two variables, ranging from -1 to +1 (0.1 weak, 0.3 moderate, 0.5 strong). |
| Metabolic Equivalent of Task (MET) | Unit quantifying physical energy expenditure. Quiet sitting equals 1 MET; brisk walking is roughly 3–4 METs. MET-hours capture total cumulative activity volume. |
| GRADE Framework | Grading of Recommendations Assessment, Development and Evaluation: A systematic international scoring system rating evidence certainty as High, Moderate, Low, or Very Low. |
| Intention-to-Screen Analysis | Evaluating intervention efficacy based on everyone invited to screen, rather than only those who attended, providing realistic real-world efficacy estimates. |
| Pack-Years | Quantifies cumulative smoking exposure: packs smoked per day multiplied by years smoked (e.g., 1 pack daily for 30 years = 30 pack-years). |
| Body Mass Index (BMI) | Body mass divided by the square of body height (kg/m²), serving as a standard population screening metric for adiposity. |
| Low-Density Lipoprotein Cholesterol (LDL-C) | Primary atherogenic lipoprotein directly implicated in vascular plaque formation. |
| Estimated Glomerular Filtration Rate (eGFR) | Metric assessing renal filtration performance (mL/min/1.73 m²), used to stage chronic kidney disease. |
| Hepatitis B Surface Antigen (HBsAg) | Serological marker indicating active Hepatitis B infection. |
| Human Papillomavirus (HPV) | Viral family responsible for nearly all cervical carcinomas; preventable through vaccination and screening. |
| Low-Dose Computed Tomography (LDCT) | Chest CT screening utilizing 15–20% of conventional CT radiation to detect early pulmonary malignancies. |
| Fine Particulate Matter (PM2.5) | Atmospheric airborne particles <= 2.5 micrometers in aerodynamic diameter, capable of deep pulmonary alveolar penetration. |
| NOVA Classification | Dietary categorization system grouping foods by degree of industrial processing; Group 4 represents ultra-processed formulations. |
| Loan Prime Rate (LPR) | Benchmark interest rate established by commercial lenders, governing consumer mortgages and legal caps on private loan interest. |
| Binding Final Arbitration | A statutory labor dispute resolution mechanism where the arbitration award is final and directly enforceable, preventing employer appeals. |
| Crude Marriage and Divorce Rates | Annual number of registered marriages or divorces per 1,000 population. |
| Automated External Defibrillator (AED) | Portable electronic device that diagnoses life-threatening cardiac arrhythmias and administers therapeutic defibrillation. |
| Cardiopulmonary Resuscitation (CPR) | Emergency lifesaving procedure combining rhythmic chest compressions and ventilation to maintain cerebral perfusion during cardiac arrest. |
| Mandatory Product Certification (3C) | Statutory safety certification required before specified manufactured goods can be legally sold or distributed. |
