I have only a-levels, but I turned down a place at uni to do civil engineering to go farming! I could have done it, but didn’t. I suspect there are many like me out there, had the ability, but not the desire. I don’t think my iq has faltered because of it! The days of sending the smart ones away to make a living and allow the dunce to farm are long gone. Farming now is not only knowing land and animals, and what to do with them, but also the myriad of paper that surrounds it. Paperwork and getting dirty don’t often go together, but farming is one of the places it does!
