The Great Lifespan Escape
At the time when the lines begin, in the mid-18th century, life expectancy in Europe and the Americas was around 35, where it had been parked for the 225 previous years for which we have data.3 Life expectancy for the world as a whole was 29. These numbers are in the range of expected life spans for most of human history. The life expectancy of hunter-gatherers is around 32.5, and it probably decreased among the peoples who first took up farming because of their starchy diet and the diseases ... 1

American Exceptionalism Prevents Americans from Recognizi...
Americans enjoy lower qualities of life on every single indicator that you can possibly think of. Life expectancy in France and Spain is 83 years, but in America it’s only 78 years — that’s half a decade of life, folks. The same is true for things like maternal mortality, stress, work and leisure, press freedom, quality of democracy — every single thing you can think of that impacts how well, happily, meaningfully, and sanely you live is worse in America, by a very long way.

Rebuking the "Good Old Days"
When you hear someone longing for the "good old days," take it with a grain of salt. (Laughter and applause.) Take it with a grain of salt. We live in a great nation and we are rightly proud of our history. We are beneficiaries of the labor and the grit and the courage of generations who came before. But I guess it's part of human nature, especially in times of change and uncertainty, to want to look backwards and long for some imaginary past when everything worked, and the economy humme... 1 notes

The Actuarial Math of Altruism
I have talked in elemental
terms of suicidal genes for saving the lives of particular numbers of kin
of exactly known relatedness. Obviously, in real life, animals cannot be
expected to count exactly how many relatives they are saving, nor to
perform Hamilton's calculations in their heads even if they had some way
of knowing exactly who their brothers and cousins were. In real life,
certain suicide and absolute 'saving' of life must be replaced by statistical
risks of death, one's own and oth... 1 notes
notesIt's not just intra-species, but the closer the relative the more altruism. Also the potential to reproduce affects the relationship as well.

Science is the "Crucible" for Extending Life
People are living longer and societies are getting grayer. You hear about it all the time. You read about it in your newspapers. You hear about it on your television sets. Sometimes I'm concerned that we hear about it so much that we've come to accept longer lives with a kind of a complacency, even ease. But make no mistake, longer lives can and, I believe, will improve quality of life at all ages.
Now to put this in perspective, let me just zoom out for a minute. More years were added to av...

Adventists Live Longer
In America here, life expectancy for the average woman is 80. But for an Adventist woman, their life expectancy is 89. And the difference is even more pronounced among men, who are expected to live about 11 years longer than their American counterparts. Now, this is a study that followed about 70,000 people for 30 years. Sterling study. And I think it supremely illustrates the premise of this Blue Zone project.
This is a heterogeneous community. It's white, black, Hispanic, Asian. The only t...Habits and characteristics of Adventists that may lend to their longer lifespans.

The Importance of Reducing Mundane Risks
Life expectancy for a healthy American man of my age is about 90. (That’s not to be confused with American male life expectancy at birth, only about 78.) If I’m to achieve my statistical quota of 15 more years of life, that means about 15 times 365, or 5,475, more showers. But if I were so careless that my risk of slipping in the shower each time were as high as 1 in 1,000, I’d die or become crippled about five times before reaching my life expectancy. I have to reduce my risk of shower...Folksonomies: statistics risk
Folksonomies: statistics risk
1 If the risk of dying by falling in the shower is only 1 in a 1,000, then a shower would kill someone in just a few years. We concern ourselves with risks that are out of our control, but we should be vigilantly mindful of the mundane daily risks we take on a regular basis, like driving our cars, standing on a stepladder, or taking a shower.
