We humans have all kinds of trouble because we did most of our evolving long before there was technology or even agriculture. For example:~ Roedy (born: 1948-02-04 age: 62)
- We crave high calorie foods, a great strategy in a world where calories are hard to find.
- We are constantly on guard, a great strategy in a world where predators attack you daily and strangers will usually try to kill you.
- We have more than two children, a great strategy in a world where most children die of infectious diseases or starvation.
- We create the most lethal weapons our imaginations can concoct, a great strategy in a world where all other animals have teeth and fangs and we do not.
- We try to be as sedentary as possible, again a great strategy in world where calories are scarce and you have to work hard to dig/find/hunt your own food.
- We have no fear of speed, a great strategy in a world where the fastest you could go was the fastest you could run.
