My son graduated with a degree in economics. He then decided to join the Peace Corps. Were they interested in his economic degree??? No, they signed him up because of his knowledge of animal husbandry which he learned from his dear old MOM!
All that grumbling about feeding, watering, cleaning, and managing the goats, chickens and horses......(do not get the picture that this poor lad was out there doing all this by himself!!) Now he is a paramedic and I absolutely believe that a relatively small part of his knowledge is scientific/medical and a large part is the framework of how to give care, and came from learning in real life. A sick goat can teach you a lot!
