Umm...I'd watch that broad brush. I can think of a number of conservative guys who wouldn't dream to do anything like that kind of work. They are smart at what they do for a living, but they wouldn't dream of or are lost when it comes to a toolbox. Not exclusive to DUmmies I'm afraid.
Maybe it's just me, but I find that anything I decide to do with my hands, I can handle.
Mechanical, electrical, HVAC, plumbing, welding, carpentry, masonry, tile....All of it comes naturally to me. Heck, my dad taught me how to weld when I was 11, I was driving tractors when I was 8, and I'm talking the 100hp big boys, not L & G tractors.
I wired and plumbed my dad's home addition when I was 14, taught myself HVAC and air conditioning at 18.
When you grow up on a dairy farm, you learn to do a lot of this stuff, or pay thru the nose to have someone else do it....
I dunno, maybe I'M the "odd bird" here....

Meanwhile, I have an automatic transmission to rebuild....
