We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
I assume this is more or less correct for right now in the U.S. (maybe Canada and Australia too). It could change in a heart beat. For example in the 30's and 40's in Europe none of these were even close to the number one cause of death.
Also, everyone dies. One doctor has said the best way to die is from a massive heart attack in your sleep at 85. So what this list should show is the cause of "early" death. That would be more relevant for the majority of us.
I am old enough that four of my siblings died very young in the 30's and 40's from diseases that we now can prevent with vaccinations. This would have been a different list before Dr. Salk and the discovery of anti-biotics. It may well be a very different list in 10 or 20 years.
The odds of dying in an asteroid strike are 1 in either 700K or 1.6MM? Not buying that one. They're more like 1 in the entire population of the globe throughout history. It's one of the few causes of death whose probability can be safely set at exactly zero.
