My 1st husband was a PE-a very good one-he and I both grew up on small family ranches in a remote area with little exposure to big cities before we went to college. He had a 160 IQ and loved to solve construction problems and make/build practical things from a very early age. Humans have never been dumb-I’m sure there were high IQ individuals who liked to make tasks more efficient, productive, etc since there was a group of humans who set up a hunting/gathering co-op and living space in a cave during the last ice age, someplace in Europe or Asia-no ancient aliens required-just my dos centavos...
#43 democrats in the area mucked things up and we kept being sent into the dark ages.
