Yes, I have literally said multiple times that I have personal experience working one of these jobs. From age 14 to 20 I worked on a dairy milking 800 head of cows, feeding them, scraping their barns and bottle feeding the calves. We did it without air conditioning in 110° heat and humidity, and we did it without heating in -25° cold and snow, because no matter how much I didn't want to work, those cows needed to be milked and fed.

It was tough physical work, and believe it or not most of my coworkers were in fact women, including my own sisters when they were old enough to get a job.
