I've spoke about this before but haven't put up this video yet. Dan explains his findings in 3 different areas where there is greater longevity in those that follow certain habits. The most consistent thing is that the poeple who live the longest were mostly vegetarian, they ate little meat and tended to be bean eaters. Seventh Day Adventists for example live upto 10 years longer than the average californian americans and they don't smoke, they don't drink, and they are vegetarian. However they are NOT on CR... as I've previously mentioned their BMI's are around 24 on average (Normal is 18.5-25).
Here are the survival curves for SDA Men and Women
"When vegetarians are forced to take medium-
risk values for all other covariates in the statistical
model, the corresponding expected ages at death are 85.3
and 88.6 years, respectively (Figures 3 and 4)"
Ten Years of Life; Is it a matter of choice?

Background: Relative risk estimates suggest that effective
implementation of behaviors commonly advocated
in preventive medicine should increase life expectancy,
although there is little direct evidence.
Objective: To test the hypothesis that choices regarding
diet, exercise, and smoking influence life expectancy.
Methods: A total of 34192 California Seventh-Day Adventists
(75% of those eligible) were enrolled in a cohort
and followed up from 1976 to 1988. A mailed questionnaire
provided dietary and other exposure information
at study baseline. Mortality for all subjects was ascertained
by matching to state death tapes and the National
Death Index.
Results: California Adventists have higher life expectancies
at the age of 30 years than other white Californians
by 7.28 years (95% confidence interval, 6.59-7.97
years) in men and by 4.42 years (95% confidence interval,
3.96-4.88 years) in women, giving them perhaps the
highest life expectancy of any formally described population.
Commonly observed combinations of diet, exercise,
body mass index, past smoking habits, and hormone
replacement therapy (in women) can account for
differences of up to 10 years of life expectancy among
Adventists. A comparison of life expectancy when these
factors take high-risk compared with low-risk values
shows independent effects that vary between 1.06 and
2.74 years for different variables. The effect of each variable
is assessed with all others at either medium- or
high-risk levels.
Conclusions: Choices regarding diet, exercise, cigarette
smoking, body weight, and hormone replacement
therapy, in combination, appear to change life expectancy
by many years. The longevity experience of Adventists
probably demonstrates the beneficial effects of
more optimal behaviors.
