- ACM: All-Cause Mortality
- Live longer
- Reduce all-cause mortality by 66.67%
- Increase life expectancy by ~20 years
- Maintain dopamine
- Main reference: There are relatively many academic literature on ACM , which can be used as the main reference
- Increased life and ACM is nonlinear : Obviously, the relationship between increased life and ACM is a nonlinear function, which is assumed here. DeltaLifeSpan=(1/(1-ACM)-1)*10
- Variables cannot be simply superimposed: Obviously, the independent and identical distribution assumptions are not met between the variables, and the actual impact between the variables is not clear
- There are contradictory views: all the evidences have literature / study correspondence, but note that: some literatures have significantly contradictory views (such as the contradiction of carbohydrate intake ratio ) ; Sleeping increases all-cause mortality by 43% )
- Research only expresses correlation: all the literature shows correlation rather than causation, and you should consider whether the literature fully proves causation when reading - such as a study which shows that people who take >=7000 steps per day have significantly lower all-cause mortality rate. However, people with fewer steps may include more long-term patients. If this data is not reasonably excluded, the literature survey will be distorted .
- Solids: Eat white meat ( -3%~-11% ACM ), mainly vegetables and fruits ( -17%~-26% ACM ), eat more spicy food ( -23% ACM ), eat more nuts ( -4%~-27%) ACM ), eat less egg yolk ( otherwise +7% ACM/0.5 pcs / day), moderate carbohydrates, eat more vegetable protein ( -10% ACM )
- Liquid: drink coffee ( -12%~-22% ACM ), drink milk ( -10%~-17% ACM ), drink tea ( -8%~15% ACM ), drink less or no sweetened beverages (otherwise One glass per day +7% ACM , + dopamine), quit drinking or within 100g per week ( pure alcohol (g) = drinking amount (ml) × alcohol concentration (%) × alcohol density 0.8g/ml ) ( otherwise +~ 50% ACM , no cap )
- Gas: no smoking ( otherwise +~50% ACM , -11~-12 years lifespan )
- Light: Sunbathing ( -~40% ACM )
- Drugs: Metformin ( +3 years for diabetics compared to normal), Multivitamins ( -8% cancer risk), Spermidine ( -30 %~-60% ACM ), Glucosamine ( -39% ACM )
- Exercise : 45 -minute swing 3 times per week ( -47% ACM )
- Everyday: Brush your teeth ( -25% ACM )
- Sleep: 7 hours of sleep per day has the lowest all-cause mortality; and the best time between 22-24 o'clock , early bed *+43% ACM **, late bed **+15% ACM *( controversial )

Increased red meat intake is associated with risk of death. Respondents who, on average, increased their red meat intake by at least half a serving per day over an average of eight years (a half serving equals 14 g of processed red meat or 40 g of unprocessed red meat) had a 10 % increased risk of all-cause mortality over the next eight years ( HR, 1.10 ; 95%CI, 1.04-1.17 ); eating two servings of red or processed meat per week (but not poultry or fish) was associated with a 3% increased risk of all-cause mortality

The all- cause mortality rate was 21.6 %, while the all-cause mortality rate for participants who did not consume chili peppers was 33.6 %. People who ate spicy food more than 4 times a week had a 23% lower risk of overall mortality and a 34% lower risk of cardiovascular death compared with those who ate no spicy food or rarely (less than twice a week) .

these participants , the researchers found that carbohydrate (sugar, starch, and fiber) and protein intake were non-linearly associated with all-cause mortality, while fat was linearly associated with all-cause mortality. Among them, higher sugar intake was associated with a higher risk of all-cause mortality and cardiovascular disease, while higher saturated fatty acid intake was associated with a higher risk of all-cause mortality .

During follow-up , the hazard ratios for all-cause mortality compared with never smoking were 1.17 ( 95% confidence interval 1.10-1.25 ) and 1.54 ( 1.42-1.67 ) for <10 cigarettes per day or ≥10 cigarettes per day, respectively ). Hazard ratios were similar regardless of age or gender. The diseases most closely associated with daily smoking are respiratory cancers, chronic obstructive pulmonary disease, and gastrointestinal and vascular diseases.

Spermidine is the most easily absorbed polyamine from the human gut. Spermidine is found in high amounts in many foods, such as fresh green peppers, wheat germ, cauliflower, broccoli, mushrooms and various cheeses, especially in soy products such as natto, shiitake mushrooms and durian. In this experiment, researchers selected 829 participants aged 45-84 years and followed up for 20 years to analyze the association between dietary spermidine intake and human mortality. potential association .
-
The study found that women's spermidine intake was higher than men's, and the intake decreased with age. The main sources of spermidine were whole grains ( 13.4% ), apples and pears ( 13.3% ), salads ( 9.8% ), sprouts ( 7.3% ) and potatoes ( 6.4% ). The study divided the population into three groups based on spermidine intake, low intake ( <62.2 µmol /d ), moderate intake ( 62.2--79.8 µmol / d ), and high intake ( > 79.8 µmol /d ). A total of 341 deaths were recorded during follow-up , including 137 from vascular disease, 94 from cancer , and 110 from other causes . The crude mortality rates for the low, middle, and high groups were calculated to be 40.5% , 23.7% , and 15.1% , respectively. These data indicate a significant inverse relationship between spermidine intake and all-cause mortality. The relationship remained significant with gradual adjustment for age, sex, and calorie ratios .

Subvert cognition! A Canadian study found that going to bed early may be more harmful than staying up late. What time is the best time to go to bed ?
-
One of the conclusions is that bedtime is strongly associated with all-cause mortality. Going to bed too early and going to bed too late can affect health, but early going to bed increases all-cause mortality more than late going to bed, and early going to bed increases 43% risk of death , while going to bed late increased the risk of death by 15% .
-
There are still many limitations in this investigation and study. For example, it does not directly prove the relationship between bedtime and death, but only shows the correlation. The data is not objective enough to count sleep time through self-report of the participants.

Pessimism is associated with higher all-cause and cardiovascular mortality, but optimism is not protective
-
In 1993-1995 , a study of healthy twins in Australians over the age of 50 included the Life Orientation Test ( LOT ), which included items of optimism and pessimism. After an average of 20 years, participants were matched with death information from Australia 's National Mortality Index. Of the 2,978 participants with many available scores, 1,068 died. Survival analyses tested associations between various optimism and pessimism scores and mortality from any cause, cancer, cardiovascular disease, or other known causes . Core on the age-adjusted pessimism scale was associated with all-cause and cardiovascular disease mortality ( hazard ratio per 1 standard deviation unit, 95 % confidence interval and p -values 1.134 , 1.065--1.207 , 8.85×10--5 and 1.196 , 1.045--1.368 , 0.0093 ), but did not die from cancer. The correlation between optimistic and pessimistic scores was weak (age-adjusted rank correlation coefficient = -0.176 ), but not significantly associated with overall or cause-specific mortality. Reverse causality (diseases that cause pessimism) is not possible, because in that case both cardiovascular disease and cancer cause pessimism .

The results showed that a total of 5414 participants were included, with an average age of 46.7 years, including 2766 women. Higher net worth is associated with a lower risk of death. Among siblings and twins in particular ( n =2490 ), a similar association was observed between higher net worth and lower mortality, suggesting that siblings or twins with more wealth were less wealthy than those with less wealth Siblings / twins live longer .
