My grandfather was a poor farmer/construction worker, who never went past the 8th grade.
I grew up watching him design and construct complex buildings for our farm out of trees we cut down, and lumber we purchased--complete with electricity and plumbing. He designed those in his head, and used a napkin when necessary. That includes all the wood beams' sizes, lengths, quality, weight and load requirements, etc. Those buildings are still standing and being used today, 50 years after they were built.
One's profession does not equal one's intelligence.
Agreed. Teacher317 completely missing the mark here.
Of course, teachers among the lowest IQs of college graduates...
