In general I am not a fan of dogs (though we had two fine Springer spaniels when the boys were young) and find the Internet obsession with "adorable" pet videos especially nauseating.
Dogs, however, (and, of course, cats) are smarter than humans in one respect--they do not smoke nor drink (unless some stupid owners rig it so they do). Frankly, eating garbage and excrement and mice is less dangerous than using tobacco and alcohol.
Forget guns, foodie falsies, climate change, politics, vaccination lies, influenza, illicit drugs, and terrorism. The biggest killers of humans are those substances that are used legally and voluntarily--tobacco and alcohol.
There are huge American industries that depend on the capacity and ability of humans to systematically kill themselves with these noxious poisons. And these industries get even richer when they induce people in developing and poor nations to waste their resources on obtaining these "luxuries". It's disgusting and immoral!
Recent reviews of these medical evils in the New England Journal of Medicine share the data that document that these poisons do even more damage than previously thought. In addition, the major benefits of quitting smoking and drinking lightly (NOT in "moderation") are outlined.
As a person who cares for others in any capacity--health care worker, friend, family member, co-worker--the best thing any of us can do is nag at people who indulge in these toxins until they quit.
NOTE: There are no such things as "victimless" crimes or self-destructive acts. The people who love and care for the willfully self-destructive suffer--BIG TIME. Just ask them!
