Count the missing fingers...
And farmers can be just as smart as anyone - in fact, most of the farmers I know are part-plumber, part-electrician, part-carpenter, part-heavy-equipment-operator, part-vet, part-mason, and part-mechanic... Nothing can wait, on a farm, and farmers are kind of, well, desensitized to pain first, then what might cause pain, by extension.
I loved living on the farm.
I don't ever want to be a farmer.
