Perhaps, but I was thinking of the typical farmer. A lot of dairy farmers know a lot about everything, inc. inputs & outputs. And they are constantly having to perform calculus to fertilize the right amount of crops or grassland, maintain nitrogen levels, rotate grazing areas, manage air pressures & energy needs, improve ph & protein in feed, move variety of machinery & animals, apply for investment grants, forward sell produce back to the market. Not to mention shave off minutes in their days to become more efficient, by expanding or upgrading operations. Maybe I’ve become a bit too obsessed with farmers of late, but they are underrated heroes.
