What are the potential implications of global depopulation?
The world population has been growing since antiquity, interrupted by wars, disasters, pandemics, and famine. But the global human population may soon hit an inflection point and enter a period of demographic contraction.
The population is already declining in many countries, including Japan, Brazil, China, Germany, Italy, Hong Kong, Singapore, Kazakhstan, Ukraine, Belarus, Moldova, Estonia, Latvia, Lithuania, Bulgaria, Georgia, Armenia, Bosnia, Croatia, Slovenia, and Hungary.1 Many more are on the brink. If it were not for international immigration, both the United States and the EU would have declining populations today. The total population of the continent of Europe, including Russia and non-EU countries, peaked in the year 2000.
Why Teach Humor?
“The most wasted of all days is one without laughter,” said the poet E.E. Cummings. Those who trigger our laughter with their humor are the people we want to spend time with, work with, or date. Humor opens our eyes to unexpected possibilities in the world, relieves our stress, improves our health, ameliorates an awkward situation, and increases our influence on others. It is widely assumed that people who are funny were born that way and so the development of a sense of humor and an ability to be humorous is left largely to the luck of the draw — your family circumstances or the television shows you watch.
Those of us who grew up in a mainstream educational system were taught reading, writing, and arithmetic in school. Anyone cracking jokes in the back of the room was fined with twenty-thirty minutes in a minimum-security afterschool detention center. Now, we know that the humor that institutions failed to appreciate when we were children can help us tremendously in professional, romantic, and social settings. So, what can we learn from the kid in the back of the room? What if we approach to humor as a skill that carries as much weight in our daily lives as reading, writing, and arithmetic? Certainly more than algebra!
Some scientists call for a bigger dose of evolution in doctors’ educations
By MITZI BAKER
Joon Yun, MD, began considering how evolution applies to human health a decade ago when his first heart disease patients died. These cases disturbed Yun, then a Stanford radiology resident. But they also intrigued him.
Having studied evolutionary biology in college, Yun tried fitting these medical failures into that framework.
His mind wandered to the early days of humans when heart disease was a rare trigger of death. In the prehistoric era, a more likely cause of death would have been an attack by a predator. The human body’s response to trauma handles this type of assault by immediately springing to action: The blood forms clots and the blood vessels tighten, together with slowing blood loss, and inflammation kicks in to combat infection. The genes governing these responses to trauma presumably were favored during evolution and have become the “factory setting” in modern humans.
