so your behind thanks. I'd guess that welders and farmers actually have a high IQ but I wouldn't know since I've never seen a peer reviewed study on such a thing
I can tell you they have extremely well developed spatial reasoning, particularly carpenters and specialty metalcraft bc you can't do the work otherwise. Some of them can "see" the completed project and do things amazingly fast.pic.twitter.com/JQinrSUjWo
