Buddy in college was a future vet. Spent a summer collecting hog semen. Stories he told me the next fall about it and the occasional "misfires" were truly horrifying.
My uncle bred cattle for decades so he was on the other side of it...
Come to think of it he did a hell of a lot of jobs. He was in the Navy during WWII, and worked as a barber after the war. He tested milk, bred cows, was a high school custodian, a handy man, did lawn care.... I definitely missed over half of the jobs he did in his day.
And that doesn't even include what his alcoholic dad made him do to survive when he was growing up on the Mississippi River. He was delivering moonshine and a bunch of other illegal stuff.
